Walnuts, like almonds, avocados, flax seeds and other things rich in good oils and antioxidants, are among the rising stars of the American whole foods health craze. But it never took a good word from Dr. Oz or Oprah to make this nut a favorite in the Périgord region of southern France, where walnuts have flourished for centuries. Mature orchards line the highways and carpet the Dordogne River floodplain, plots of sapling twigs sprout their first year’s leaves in adjacent plots, trees blossom with the promise of a bumper autumn crop, and heaps and heaps of nuts are sold in bulk in virtually every single market. Deeper inside the local shops and households, one finds other things walnut–including fresh-pressed oil and whiskey-strong walnut booze. And following the road signs of the “Route de la Noix,” a meandering circuit of small highways through the woods, travelers discover the Périgord’s most prolific walnut country–and along this route are walnut oil presses, walnut museums, distilleries, and places to taste the Périgord’s variety of other walnut products. I, as it happens, am on vacation here, and for at least a few days I’m disregarding the region’s foie gras, truffles and wine and, instead, am making this visit to the Dordogne Valley a walnut tasting tour.

Here are five ways I’ve recently learned to enjoy this rising superstar of nuts:

1. Drink it: Eau-de-vie de noix. This liqueur–translated into something like “firewater of walnut”– begins as brandy, distilled from wine, but gains its distinguishing marks through several weeks of sitting on mashed-up walnuts. The final product, which may never touch an oak barrel, is usually just faintly yellow with a subtle candy-like nuttiness. The drink is dry–unsweetened–and usually weighs in at about 42 percent alcohol by volume. (Don’t get it mixed up with drinks like vin de noix, eau de noix or liqueur de noix, discussed below.) Drink eau-de-vie de noix straight or on the rocks to best savor its subtle essence–and in the name of France’s cherished food-and-drink traditions, keep the expensive bottle away from that hair-gelled mixologist friend of yours.

2. Drink It, Part II: Walnut wine. You’ll see this billed as “vin de noix” in the Perigord, yet the product is grape-based, made from straight red wine that sits on macerated green walnuts (harvested in the summertime, when bitter and scarcely edible) for several weeks before being sweetened with sugar and sometimes spiked with brandy or vodka. Many households make this drink, as do inns where it may be served to guests. Relatively little is labeled and sold commercially, but visitors to the Dordogne Valley (it occurs in Italy and the Balkans, too) will have little trouble finding a glassful. Walnut wine usually runs about 16 percent alcohol by volume. But those who read bottle labels will observe that a similar product called “eau de noix” runs 18 percent, and that another labeled as “liqueur de noix” measures about 30. They are different renditions of the same recipe. Speaking of which, walnut wine is almost stupid-easy to make yourself; you need just green walnuts, wine, sugar, brandy and a few weeks.

3. Drizzle It: Walnut oil. This is one of those oils that can be so delicious that one hates to do anything with it much more complicated than sipping it from a spoon. It is a product of the autumn, when the walnuts fall by the tons and tons throughout the Périgord. Many farmers rake up at least part of their crop and bring it to the local oil maker. Here, a grinding mill–sometimes decades old–smashes the nuts, rendering a honey-golden juice that comes gurgling out into jugs. Often the walnuts are toasted before being ground, though some farmers of less traditional tendencies are now “cold-pressing” the nuts for a subtler, softer oil–and supposedly with more health benefits. You may find roasted walnut oil to be superior. It is fragrant, rich, warm and toasty. Don’t even think of blending it with balsamic (even though the locals often do, perhaps since they have all they can use), and if you must make a dressing with it, go easy on the vinegar. Also, don’t use walnut oil for cooking, as high temperatures can supposedly annihilate its purported health benefits and burn away its aromas. The best ways to taste walnut oil may be to drizzle it over couscous, charcuterie, a runny egg yolk or a steaming plate of whole-grain bulgur.

4. Eat It: Walnut Bread. The humble baguette may be the oven-made star of the French boulangerie–but walnut bread is better. Produced year-round and available in most good bakeries, walnut bread–sometimes made with whole wheat for a richer, fuller flavor–is often baked into a round loaf with a hard crust, and the nuts are inevitably toasted. Layer a slice with cheese–or drizzle it with walnut oil.

Many sorts of breads in France trump the plain baguette, such as these morning loaves of fresh walnut bread spotted in the village bakery of Saint Julien de Lampon. Photo by Alastair Bland.

5.  Spread it: Walnut cheese. Another specialty of the Périgord, walnut cheese may be encountered as a sticky Tomme-like substance called Echourgnac, made at the Trappist Abbey of Our Lady of Good Hope and soaked in walnut liquor. This treatment produces a strong-tasting and smoky scent–almost like cured anchovies–yet subtle in the walnut spectrum of flavors. One must consciously wish to taste walnut to believe he actually can–but the label of the Trappe Echourgnac, a 14-ounce walnut cheese wheel, verifies that, indeed, the stuff is bathed in “liqueur de noix.” Want a crunchier experience? Try Gourmandise, a blended cheese studded with crumbled walnuts.

When we think about pigs today, most of us likely imagine the Wilbur or Babe-type variety: pink and more or less hairless. Mention pig farming and images of hundreds upon hundreds of animals crammed into indoor cages may come to mind, too. But it wasn’t always like this. Prior to the industrial revolution, pigs came in an astounding variety of shapes, sizes, colors and personalities. And the ham made from their cured meat was just as diverse.

“The tale of ham’s innovation began around 200 years ago, and it paved the way for how ham is produced today,” said Nicola Swift, the creative food director of the Ginger Pig, a company of butchers and farmers that specializes in rare breeds of livestock reared in England’s North York Moors. Swift presented a talk on the history of ham at the BACON conference in London last weekend, which sadly was not devoted to bacon but to “things developers love.”

One family in particular, the Harrises, almost single-handily changed the way England turned pigs into ham, she explained, and in doing so, they inadvertently laid the foundations for large-scale, homogenized pig farming.

Mary and John Harris were pig folk. Their family hailed from Calne, a quiet town in Southwest England. In the early and mid-1800s, they played a small but important role in providing London with pork. At the time, much of London’s pork arrived by way of Ireland. But without refrigeration, transporting large amounts of meat was impossible. Instead, pig handlers would literally walk the animals to the Irish coast, corral them onto boats destined for Bristol, and then continue to trek to London by foot.

But a deliciously fat pig forced to trot more than 100 miles would soon turn into a lean, tough mass of muscle. To make sure the ham, chops and bacon that those animals were destined to become remained fatty, tender and flavorful, pig herders would make pit stops along the way to give the animals a rest and fatten them up. The Harris farm was one such destination. The family also supplied Calne with meat from their small shop on Butcher’s Row, founded in 1770.

The Harrises were by no means well off. If they butchered 6 or 8 pigs in a week they wrote it off as a success. Still, they got by all right. That is, until tragedy struck. In 1837, John Harris, the relatively young head of the household, died suddenly, leaving his wife, Mary, to manage the business and look after the couple’s 12 children. A few years later, just as the family was getting back on its feet, hard times fell upon them once again. It was 1847, and the Irish potato famine arrived.

In Ireland, potatoes fed not only people but their pigs, too. As season after season of potato crops failed, the Irish could not feed themselves, much less their animals. The supply of pork to the Harris’ farm and butcher shop stopped arriving. In desperation, Mary and her son, George, hatched a scheme to send George to America by ship. The idea, they decided, was for George to strike up a pig business deal with American farmers and figure out a way to transport their slaughtered animals across the Atlantic in boxes packed with salt to ward off spoilage during the long journey. On its way to England, that meat would cure into ham and George’s entrepreneurial venture would save the family.

Not surprisingly, George failed in his mission. But while in the States, he did learn of a remarkable new practice the Americans were pursuing called ice houses. In the U.S., this method allowed farmers to slaughter pigs not only in months ending in an ‘r’ (or those cold enough for the meat not to rot before it could be cured and preserved), but during any time of year – even in steamy July or August. Curing, or the process of preventing decomposition-causing bacteria from setting in by packing the meat in salt, was then the only way to preserve pork for periods of time longer than 36 hours. Such horrendously salty meat was eaten out of necessity rather than enjoyment, however, and it often required sitting in a bucket of water for days at time before it could be rinsed of its saltiness to the point that it would even be palatable. ”This all harks back to the day when people had to preserve something when they had lots of it because there were other times when they didn’t have much,” Swift said. “This type of preserving goes back hundreds and hundreds of years.”

Ice houses, specially constructed sheds with packed ice blocks either collected locally or imported from Norway, offered partial relief from that practice, however. Charcoal acted as an insulator, preventing the ice from melting quickly and trapping the cool air within the small room.

When George returned home, curly tail between legs, he immediately got busy earning back his family’s trust by experimenting with ice house design. By 1856, he had succeeded in constructing what was likely the first ice house in England. The ham that resulted from slaughtering pigs in that cool confine was more tender and tasty since it didn’t have to be aggressively cured with large amounts of salt. Eventually, the Harrises shifted to brining techniques, or curing in liquid, which led to the creation of the massively popular Wiltshire ham.

The family patented George’s creation, and it soon began spreading to other farmers and ham producers who licensed the technology around the country. The Harris’ wealth increased so quickly and so dramatically that they partly financed the construction of a branch of the Great Western Railway to their village in 1863. Several decades after that, they helped bring electricity to Calne.

While the Harris’ tale is one of personal triumph, their mark on England’s ham production did not come without cultural costs. Prior to the ice house, each region in the UK and Ireland enjoyed their own specific breed of pig. In Lincolnshire, for example, Lincolnshire ham originated from the Lincolnshire curly coat, an enormous beast of a pig that was around twice the size of the animals typically bred today. It’s long, thick curly white coat kept the hardy animal warm throughout the damp winters, and its high fat content provided plenty of energy for the farm laborers that relied upon its exceptionally salty ham for sustenance. After a long decline, that breed finally went extinct in the 1970s thanks to industrialized farming.

Other regions once boasted their own breeds and unique ham brews. In Shropshire, people made “black ham,” which they cured along with molasses, beer and spices. This created an exceptional mix of salty sweetness, with a tinge of sourness from the beer. In Yorkshire, a breed called the large white – which is still around today – inspired a method of steaming cured ham in order to more efficiently remove the salt, while in Gloucestershire people preferred to add apples to their ham cures. But after the Harris’ ham empire took off, a massive advertising campaign that followed painted a picture of what ham and bacon should look and taste like, largely removing these traditions from kitchens around the country. “Most of the regional variances are sadly not known any more except to ham geeks,” Swift said.

In addition to stamping out ham variety, the Harris’ factory – which soon employed hundreds of staff and processed thousands of pigs each week – and others like it began favoring homogenized mass-production methods of indoor pig rearing. Older residents in Calne recall the factory’s unmistakable reek in the 1930s. Eventually, public protests caused its closure and demolition in the 1960s, but for local pigs and ham, the damage was already done. Between 1900 to 1973, 26 of the unique regional breeds of pigs and other livestock went extinct, with others surviving only in very small numbers.

To try and preserve pig and other livestock heritage, concerned citizens formed the non-profit Rare Breeds Survival Trust in 1973, which maintains a sort of endangered species list and conservation group for farm animals on the fringe. In addition, farms such as Swift’s Ginger Pig specialize in breeding and reintroducing some of these lines into restaurants and local butcher shops in London and beyond, and in introducing traditional curing techniques through their upcoming book, the Farmhouse Cook Book. “Innovation is awesome and brilliant, but there’s also a dark side,” Swift said. “That’s the history of ham.”

These days, the classic wedge salad—wherein the chef smothers a chunk of crisp Iceberg lettuce with creamy blue cheese dressing, and crumbles bacon all over the top—is seen as a cornerstone of American “comfort food.”

The dish is also often credited with single-handedly causing an “Iceberg comeback.” All of this raises the question: Did this crisp salad green, the “polyester of  lettuce,” really go so far away that it needed to come back? And if so, can one menu item really make a difference?

But first a note—for those who aren’t old enough to remember—about just how ubiquitous Iceberg lettuce once was. Introduced for commercial production in the late 1940s, Iceberg (or crisphead) lettuce was the only variety bred to survive cross-country travel (the name Iceberg comes from the piles of ice they would pack the light green lettuce heads in before the advent of the refrigerated train car). Therefore, throughout the middle of the century, unless you grew your own or dined in a high-end establishment, iceberg essentially was lettuce.

Most of the nation’s lettuce is grown in California, and in 1974, leafy green “non-crisphead” varieties of lettuce still made up only around five percent of the total acres grown in California. Then things changed. For one, consumers became more aware of the nutritional value of greens that are, well, greener. (Made of a high percentage of water, iceberg has only around 1/20th the amount of vitamins as the darker leafy greens, says David Still, a plant science professor at California State Polytechnic University at Pomona.)

America’s everyday lettuce for half a century was losing market share. By 1995, other lettuce varieties made up to around 30 percent of the lettuce American’s ate, and it has been rising steadily since, according to the California Leafy Greens Research Programs (a salad industry group). That’s precisely why, by 2007, the Salinas, California-based Tanimura and Antle—the nation’s largest lettuce supplier—decided it needed to start promoting Iceberg. And rather than compete with varieties that have more flavor or nutrition, Tanimura and Antle went straight for nostalgia, and opted to draw a connection to steaks, fathers, and sports. A press release from the time reads:

Mother’s Day has strawberries, Thanksgiving has celery, but historically no holiday has been associated with Iceberg lettuce,” says Antle. “What better product to claim ownership of Father’s Day than the cornerstone salad of steakhouse menus?

Wal-Mart, Albertsons, and several other big retailers hung signs and banners promoting the campaign, and sales got a boost. The company also planted wedge salad recipes around the food media world, in hopes that they would inspire chefs to return to this American Classic.

It’s hard to say whether the Father’s Day angle made a difference, but the larger effort to reconnect to Iceberg to simpler times with fewer complicated health choices appears to have worked. Sort of.

On the one hand, chefs like the fact that Iceberg is a completely neutral way to add crunch and filler to an otherwise flavorful medley of ingredients. So it appears that this classic salad will be sticking around on menus for a while. (Last fall the San Francisco Chronicle ran a list of nearly a dozen upscale restaurants serving some variation on the wedge salad, including everything from croutons, to apple, walnuts, and avocado. One Napa restaurant even serves it with the Iceberg frozen for extra crispness.)

On the production level, however, Iceberg may never return to it’s reigning position. It’s a little cheaper to grow and has long been easy to ship and store (the name Iceberg is said to come from the way the round lettuces were shipped by train in big piles of ice), but it has a hard time standing up to romaine, butter, and all the other specialty greens that have become popular in recent years.

This also appears to be true outside the U.S. In 2011, for example, UK-based Telegraph declared: “The era of Iceberg lettuce is over,” as “bagged leaf varieties such as [arugula] and watercress are up by 37 per cent compared to last year.” Of course, it may never be hard to find Iceberg lettuce in fast food tacos and Sizzler salad bars.  But the decline of Iceberg might also signal some good news for Americans’ diets.

“Iceburg sales have gone down, but romaine has gone up,” says Mary Zischke from the California Leafy Greens Research Programs. “Tastes have changed. And the darker, leafy greens have a better story to tell from a nutrition standpoint.”

Compared to 20 years ago, Zischke added, “there are a lot more choices. Especially in some parts of the country, like the Midwest.” Overall, she’s glad to report that: “The product mix has changed, but our [greens] industry has also gotten bigger.”

An advertisement for Dole canned pineapple, circa 1940s.

The most-visited tourist attraction in the state of Hawaii is the World War II Valor in the Pacific National Monument (also known as the Pearl Harbor bombing site). The second most visited attraction is about 20 miles north: the Dole pineapple plantation. In peak season between March and July, this tropical fruit evokes the 50th state in the Union for many. It’s a strange notion considering that, of the 300 billion pineapples farmed worldwide, only 400 million come from Hawaii. That’s only .13 percent. And while it’s true that Hawaii was once the big kahuna in global pineapple production, it’s an American industry that had a meteoric rise and fall over the course of the 20th century.

While its exact origins have yet to be determined, botanists agree that the pineapple originated in the Americas, most likely in the region where Argentina, Paraguay and Brazil meet [PDF]. As to how the plant arrived, and was domesticated, in Hawaii is apocryphal. Some sources point to Spanish sailor Don Francisco de Paula Marin, who arrived in the Islands in the early 1790s. In addition to serving as an interpreter for King Kamehameha I, Marin had a reputation for being an ace horticulturalist credited with introducing citrus and mangoes to the island nation. He does, however, provide us with the first written record of this fruit in the New World, the simple January 1813 diary entry: “This day I planted pineapples and an orange tree.”

But to enjoy pineapple meant you had to buy local. In the age before refrigerated transportation, ripened fruit spoiled easily during shipment to the mainland, resulting in high losses of product. Even if pineapple were shipped green, the premature harvesting severely impacted the flavor. The 19th-century development of canning technology provided the much-needed, failsafe delivery mechanism for the fruit; however, high tariffs placed on the good exported to the mainland from Hawaii caused the first canning companies to fold. The Hawaiian pineapple industry wouldn’t take a turn for the better until the United States’ annexation of Hawaii in 1898 after the Spanish American War and the arrival of 22-year-old Massachusetts native James Dole the following year.

Despite knowing nothing about canning, Dole opened the Hawaiian Pineapple Company in 1901, which the local press begged as being “a foolhardy venture.” And in its early years, it did indeed operate at a loss. However, Dole invested in developing new technologies—notably hiring a local draughtsman to develop machinery that could peel and process 100 pineapples a minute. He was also savvy to the power of advertising. Banding together with other local growers, Dole mounted an aggressive nationwide advertising campaign to make consumers aware of his product.

Dole was certainly not the first to introduce pineapple to the mainland American market. Rather, his business savvy and the economic conditions of the times allowed him to champion the fruit. Pineapple was cultivated in Florida, but recurring frosts destroyed the crops and what survived was of sub-par quality. Baltimore had a canning industry, but its fresh fruits were imported from the Bahamas, which heightened production costs due to importation taxes. With the combination of ideal growing conditions, the consolidation of cultivation and production and advertising that asserted the superiority of Hawaiian pineapple over all competitors, Hawaii was poised to dominate the canned pineapple trade. And it did. By the 1920s, it developed into a culinary fad, most notably in the form of upside down cake. (Author Sylvia Lovegreen collects a number of recipes from this era, from classic to questionable, in her book Fashionable Food.)

By 1923, Dole was the largest pineapple packer in the world. The agricultural sector took note and pineapple industries sprung up on other islands. Between 1930 and 1940, Hawaii dominated the canned pineapple industry and at its mid-century peak, eight companies were in operation and employed about 3,000 people. After World War II, the canned pineapple industry spread to other parts of the world, namely Thailand and the Philippines. Not only did these countries provide an ideal environment for growing, but labor costs were significantly lower. (Where U.S. labor accounted for about half of the cost of production, ranging between $2.64 and $3.69 per hour, compared to the 8 to 24 cents per hour paid to Filipino workers.)

The Hawaiian industry began to collapse in the 1960s. In response, the industry tried to focus on growing and shipping fresh fruit with faster, refrigerated means of transportation now readily available. Additionally, the development of the pesticide DBCP in the 1950s was invaluable to the industry as a means of protecting the pineapple tree’s root systems from attacks by ground worms (the EPA would ban the chemical in the late 1970s).But those innovations weren’t enough. Dole’s Honolulu cannery closed in 1991 and competitor Del Monte moved production out of islands in 2008.

The state’s pineapple industry currently exists primarily to satisfy local demands, much as it did before the arrival of James Dole. It is, however, worth noting the one element we lose with pineapple produced on a global industrial scale: flavor, or rather, variations thereof. Chances are, the fresh pineapple you find in your supermarket is the MD-2 cultivar, a hybrid developed because it’s sweet, low in acid and not susceptible to browning when refrigerated—a common problem in the Smooth Cayenne, which had been Hawaii’s industry standard variety cultivated since the 1880s. But there’s a host of other varieties that come in different shapes, sizes, colors and flavor profiles.

Dissatisfied with the taste of fresh, industrially-produced pineapple, the husband and wife team of Craig and Lisa Bowden developed their own variety that evoked the flavors of fruit they enjoyed in their youth. Together, they founded Hawaiian Crown, an independently-owned company in Honolulu. Though just a 20-person operation, Hawaiian Crown has not only carved out a niche for itself in the local farmer’s markets, but is finding distribution in grocery stores. Although the fruits of Hawaiian Crown’s labors are currently available only on the islands, here’s hoping that a new wave of pineapple innovation can re-invogorate an American industry.

Give a baby her first spoonful of mashed spinach or blended brussell sprouts and you can likely watch her face pucker up in shocked torment. Veggies tend to be a dreaded childhood bane for many youngsters, yet there are exceptions to the vegetable hate rule. Sweet potatoes and carrots, for example, tend to score highly. But why is that? As a general rule, much of our likes and dislikes spawn from sweetness – or at least our perception of it.

Evolutionarily, we’re programmed to like sweetness, since it’s indicative of calorie-rich sugar. Millennia ago, when we were just beginning our evolutionary journey as Homo sapiens, those individuals who preferred and thus consumed sugar had an edge. Sugar imparts a quick energy boost, so desiring, locating and consuming sugar-rich food could mean the difference between out-maneuvering a predator, keeping warm during a cold night or bearing healthy children. Our closest relatives, such as chimpanzees, also share this propensity towards the sweet. Chimps regularly concoct creative ways to brave beehives to reach the sweet honey inside.    

In today’s world of car commutes, office jobs and sugary snacks, however, our attraction to sugar turns against us, helping to fuel an epidemic of obesity. The processed food industry realized this a long time ago when it dawned on them that cranking up the sugar content of even the most cardboard-like snack automatically makes it delicious to our primitive food brains. 

But sugar, it turns out, is not the only sweetness driver. The sweetness of a farmer’s market strawberry or a hand-picked blueberry comes largely from volatiles, or chemical compounds in food that readily become fumes. Our nose picks up on and interacts with dozens of these flavorful fumes in any given food, perfuming each bite with a specific flavor profile. The sensations received by smell and taste receptors interact in the same area of the brain, the thalamus, where our brain processes them to project flavors such as sweetness. ”The perception of sweetness in our brains is the sum of the inputs from sugars plus certain volatile chemicals,” said Harry Klee, a researcher with the university’s Horticulture Sciences Department and Plant Molecular and Cellular Biology Program, said at the American Association of the Advancement of Science conference, held last week in Boston. “The volatiles act to amplify the sugar signal so that we actually think there’s more sugar in the food than is actually present.”

A dozen or more volatiles can occupy a single food. Some trigger the sensation of sweetness, others of bitterness or sourness. If we could better understand just how these chemicals interact in foods and in our brains, we could genetically tweak foods to be more to our liking.

Scientists from the University of Florida think that “fixing the flavor” of foods such as tomatoes would make them more appealing to shoppers, which on the long run may facilitate a healthier society. “If we make healthy things taste better, we really believe that people will buy them more, eat them more and have a healthier diet,” Klee said. “Flavor is just a symptom of a larger problem,” he continued. “We have bred crops for a higher yield, while quality and nutritional value have dropped.” 

What we think of as flavor actually has a great deal to do with the subtle smells of volatiles. Not convinced? The researchers predicted as much. In Boston, they whipped out samples of gummy bear-like candy (raspberry and blueberry Sunkist fruit gems to be specific) to prove the power of volatiles to the audience. As instructed by the Klee and his colleagues, I pinched my nose shut tight, then popped the candy into my mouth, chewed and swallowed half of it. As if I had a seriously stuffed up nose from a bad case of the flu, the candy felt squishy and lackluster on my tongue. This bland sensation, the researchers explained, is taste. Now, they instructed unplug your nose, and swallow the rest of the gummy candy. A wave of intense sweetness hit me like a sugary rainbow of fruity flavor. This is olfaction at work, explained Linda Bartoshuk, one of Klee’s colleagues at the university’s Center for Smell and Taste. “Who experienced a rush of flavor and sweetness that seemed about twice as powerful as before?” she asked. In a room of around 100 people, about half the hands shot up. 

Several years ago, Klee made a mission of saving the modern tomato’s flavor in the hopes of ultimately improving consumer health. Those efforts have led him down a winding vine of chemistry, genetics and food science. 

Rather than starting his investigation with tomato growers–who are paid to churn out attractive tomatoes, not make a flavorful food–Klee began with consumers, or the people who buy and eat tomatoes. He wanted to understand what makes good and bad flavor on a molecular level. Figuring out the formula for creating a delicious tomato that still maintains the high yields and disease resilience of the watery, bland supermarket offerings could give growers an easy-to-implement toolkit for improving their offerings.  

Klee and his colleagues ground up dozens of tomato variety, then asked 100 different people to sample the fruits of the researchers’ labor and report back on their favorites and least favorites. Using that feedback, the researchers could identify which of the tomatoes’ more than 400 volatiles actually drove flavor. What they found indicated that consumers prefer tomatoes with a perceived sweetness – emphasis on “perceived.”

For example, yellow jelly beans, a breed of tomato, contain around 4,500 milligrams of sugar per 100 milliliters. A matina tomato, on the other hand, contains around 4,000 mg per 100 ml. Yet people perceive matinas as being about twice as sweet as yellow jelly beans. Volatiles drive the perception of what we think is sweetness in these two tomatoes.

Typically supermarket variety tomatoes vary in their sugar content, but they usually range from around 2,000 to 2,500 mg per 100 ml. The cherry tomato varieties typically sit in the 3,000 to 3,500 mg per ml range.

Just 15 to 20 volatiles control the majority of a tomato’s flavor, the researchers found.  ”Some of the most abundant chemicals in a tomato have absolutely no influence on whether people like it or not,” Klee said.

This knowledge in hand, they went about creating a recipe for the perfect tomato, which resembles an heirloom. Their ideal fruit represents the average of what the research participants ranked as their preferred tomato. While absolute individual preferences may vary by demographics, cultures and whether or not someone is a supertaster, Klee believes that nearly everyone would agree that “this is a really good tomato.” 

The next step, Klee says, is to move those desirable traits into the high yielding varieties of tomatoes. In the lab, he and his team successfully crossed modern tomatoes with their perfected heirloom, creating a hybrid. The new tomato maintains the deliciousness of the volatile-laden heirloom but produces twice as much fruit and keeps the modern strain’s resistance to disease. So far, yields aren’t quite at the level to convince commercial growers to change their ways, but Klee believes production improvements will get his tomato to the marketplace eventually. 

“Can volatiles enhance sweetness while reducing our use of sugars and artificial sweeteners?” Bartoshuk posed. “We think: yes.”

Is your lemon juice really citrusy sugar water?

Is that hunk of white tuna sushi actually escolar, a cheaper fish associated with its own kind of food poisoning?

And is your age-defying pomegranate juice just plain-old grape juice with a splash of the good stuff?

After winning a seat in the pantheon of so-called “super foods,” pomegranates got a burst of popularity, with consumers craving everything from fresh seeds to juices and teas. But its newfound fame also found it the victim of an age-old problem: food fraud. According to the non-profit organization U.S. Pharmacopeial Convention (USP) in Maryland, pomegranate juice was the most common case of food fraud in the past year, often watered down with grape or pear juice to cut costs.

The group operates the Food Fraud Database, which went live in April 2012 and recently added 800 new records. Other usual suspects from the scholarly articles, news accounts and other publicly available records include milk, honey, spices, tea and seafood.

Though senior director of food standards Markus Lipp says we enjoy a high level of food safety in the United States, he also warns, “The real risk of adulteration is that nobody knows what’s in the product.”

Adulteration, according to the Food and Drug Administration, includes foods in which, “any substance has been mixed and packed with it so as to reduce or lower or injuriously affect its quality or strength,” including, added poisons or deleterious ingredients. Sometimes contaminants pose severe health risks, as was the case with the tainted milk from China in 2008. But often it’s a matter of using a cheaper, but still legal product to cut another.

To avoid fraud, Lipp subscribes to the idea that if the price seems too good to be true, it probably is, particularly for liquids. And for ground foods, like spices, coffee and tea, Lipp suggests buying whole food products to have a better sense of what’s really in there.

Liquids

1. Olive Oil: Olive oil might have the distinction of being the oldest adulterated good. “Olive-oil fraud has been around for millenia,” according to the New Yorker. Cut with sunflower and hazelnut oils, olive oil was considered “the most adulterated agricultural in the European Union” by the late 1990s. Even after a special task force was formed, the problem remains. In his 2012 book, “Extra Virginity: The Sublime and Scandalous World of Olive Oil,” Tom Mueller writes about the ongoing fraud. Mueller tells the New Yorker, “In America, olive-oil adulteration, sometimes with cut-rate soybean and seed oils, is widespread, but olive oil is not tested for by the F.D.A.—F.D.A. officials tell me their resources are far too limited, and the list of responsibilities far too long, to police the olive-oil trade.”

2. Honey: In 2011, honey was at the center of the largest food fraud case in United States history, along with “a network of co-operatives in Asia, a German conglomerate, jet-setting executives, doctored laboratory reports, high-profile takedowns and fearful turncoats.” The $80-million case involved a flood of cheap honey imported into the United States after being contaminated first with antibiotics and then with “corn-based syrups to fake the good taste,” according to the Globe and Mail.  A quick search on the USP database reveals the problems persists, with added sweeteners like corn, cane and beet syrups.

Spices and Ground Goods

3. Saffron: Corn silk, dyed onion, beet fiber and sandlewood dye; these are a few of our least favorite things, that get passed off us as saffron, according to USP. Lipp says it’s particularly easy to disguise other products as higher quality spices because the fine grain hides discrepancies. “If I buy ground black pepper, I obtain a fine powder of  a gray speckled mess,” he says. But if he buys whole black peppercorns, Lipp says he can, “just by visual inspection, make sure there’s not a large amount of twigs or any other low-grade materials in it or anything else but black pepper.”

4. Tea: Suffering from a similar “speckled mess” problem as saffron, ground tea can disguise adulterants like, turmeric, copper salts and even sand and colored sawdust, according to database results. Loose leaf teas may offer a more reliable route, plus you can take up a cool new hobby and learn to read tea leaves.

5. Wasabi: You watched Jiro Dreams of Sushi and now you’re eating your way through all the Japanese eateries within a 50 mile radius, but–and no disrespect to the fine establishments you frequent–are you actually eating real wasabi? That kick in the sinuses may actually be courtesy of horse radish, mustard and food coloring, not paste made from grated wasabi root. Fortunately, horseradish still manages to get the job done but if you want the real thing, you may have to do some digging.

6. Sriracha: This “hipster ketchup” that is “so popular, that people are counterfeiting it,” recently got the rundown on the radio show, The Dinner Party. The mix of jalapenos, garlic, sugar, salt and vinegar comes in an iconic rooster-stamped, green-capped bottle from California’s Huy Fong Foods. And though there is a town in Thailand called Sriracha, Randy Clemens, author of “The Sriracha Cookbook,” told the Dinner Party, the hot sauce there is very different from the mix hipsters love so dearly, though it involves the same core ingredients. In an attempt to capitalize on Huy Fong’s success, bottlers have begun mimicking the brand, even replacing the rooster with a unicorn in one instance. Less a matter of faked ingredients, it’s still pretty misleading and falls under the FDA’s regulations on “misbranding.” To make sure you’re getting the real Huy Fong deal, Clemens says, “You want to look for the green cap.”

Guacamole and the Super Bowl. The two go hand in hand these days don’t they?

And yet, if you visit the California Avocado Commission’s website — brought to you by the state with 60,000 acres of avocado orchards — you won’t find any mention of “Guacamole Sunday.” Instead, a message on the site’s front page reads: “Our season has ended. Look for California avocados in stores from Spring – Fall.”

When I asked Will Brokaw, the California farmer behind Will’s Avocados about this seemingly odd timing, he was quick to point to the irony.

“The California avocado season is just barely getting going at that time of year,” he said. And while it’s great that demand is so high, which in turn raises sales numbers and wholesale prices for everyone, it’s a shame to see that demand at precisely the moment when Hass avocados – the most popular domestic variety – have yet to fully ripen. (The ones that do get picked in February are often watery, he says.)

“Everybody would be better off if the Super Bowl was delayed until early March,“ Brokaw added.

Well, maybe not everybody. In fact, as soon as I started looking into how avocados became the signature food for an event that takes place in the dead of winter, it quickly became clear that the Super Bowl-guacamole tie is a fascinating – perhaps disturbing – example of the way globalization has come to define the food on our plates.

Last year, according to the produce industry publication The Packer, about 75 percent of the avocados shipped within the U.S. in the weeks leading up to the Super Bowl came from Mexico. Most of the rest came from Chile. And that translates to a lot of the creamy green fruits. This year Americans will eat almost 79 million pounds of them in the few weeks before the big game – an eight million pound increase over last year and a 100 percent increase since 2003.

None of this has been an accident. The avocado industry started promoting guacamole as a Super Bowl food back in the 1990s, shortly after the NAFTA agreement began allowing floods of avocados from Central and South America to enter the country in winter. By 2008, Mexico had become the largest supplier of avocados to the U.S.

The Christian Science Monitor wrote about the phenomenon in this 2009 article, Super Bowl success story: Mexico’s avocados.

In the central state of Michoacán, Mexico’s avocado belt, exports generated $400 million last year, and it’s now the second source of income for the state – after remittances sent from Mexicans living in the US.

“It has transformed this state, and put a hold on immigration,” says José Luis Gallardo, the head of the Michoacán Avocado Commission and a plantation owner who has watched the industry explode in the past few years.

While fresh avocados have been a staple of the Mexican diet for centuries, in the US they were mostly consumed in California or Texas, where they are grown.

Today, the fruit is as common in California supermarkets as it is in Kansas.

This is where I start to feel conflicted. On the one hand, I feel truly happy for the Kansans who now have access to one of the world’s most delicious, perfect foods. And I like knowing that so many people are serving guacamole at their Super Bowl parties instead of say, highly-processed cheese dip.

But the fact that the foreign avocado industry was able to create a new market for their product virtually overnight simply by pulling out all the stops on marketing the product as an established Super Bowl food also seems noteworthy.

Our increasing dependence on large monocrops and factory farms (think: vast swaths of almonds grown in California to feed Germany’s hankering for marzipan, or the pork produced in Iowa’s concentrated animal feeding operations (CAFOs) intended for South Korea, Colombia, and Panama) comes with a steep price.

Until just a few decades ago, most Americans had a basic awareness of the way food and farming was connected to place, seasons, and the weather. Not only have we lost these things, but we’ve also lost touch with how and where our food is produced — a key piece of the puzzle when it comes to knowing that your dinner ingredients won’t be, say, recalled for salmonella contamination, filled with antibiotics, or covered in pesticide residue.

I can call up Will Brokaw — or grab him at the farmers market — and ask him how he grows his avocados (everything from how he controls pests, treats the soil, and uses water, to how he treats his workers). And while the growers in Michoacán, Mexico, may very well be using the exact same farming practices, I have no way of knowing either way. That disconnect may not keep most of us from buying winter avocados, but it should give us pause — just like the other windows into the vast complexities of our food system should.

And that “perfect Super Bowl snack”? It may not be quite so perfect anymore.

How much would you pay for a cup of coffee? Wikimedia Commons.

When Starbucks announced in late November that it was unveiling a new $7-per-grande-cup brew in select stores, reaction was mixed. Seattle Weekly’s food writer, Hanna Raskin wrote about an office taste test, “The consensus was that the coffee’s good, but not appreciably better than Starbucks’ standard drip.” And yet, the Costa Rica Finca Palmilera Geisha has been doing okay. The Los Angeles Times reported that the online stock sold out in 24 hours, at $40 a bag.

While the news might elicit a Liz-Lemon worthy eye-roll or shooting pangs of jealousy depending on the person, it might actually be something we just have to get used to. Published just a few weeks before Starbucks unrolled its cup of liquid gold, a study from the Royal Botanic Gardens in the U.K. and the Environment Coffee Forest Forum in Ethiopia warned that up to 70 percent of the world’s coffee supply could be gone by 2080 due to climate change.

Turns out, the warnings are actually pretty consistent across the board, the World Bank is practically hoarse with all its calls for caution. On November 18, the World Bank released a new study about the effects of climate change over a long period of time, concluding, “The world is barreling down a path to heat up by 4 degrees at the end of the century if the global community fails to act on climate change, triggering a cascade of cataclysmic changes that include extreme heat-waves, declining global food stocks and a sea-level rise affecting hundreds of millions of people.”

New York University associate professor of food studies and economist Carolyn Dimitri says attention to the vulnerability of the world’s food systems is a step in the right direction but not enough. “These are really big and important groups that are talking about this, but how are they going to gain traction given the way our food system has become so industrialized?”

Carolyn Dimitri is currently working on a book about urban agriculture in 15 American cities.

As someone who’s been studying organic food marketing and access since her days at the U.S. Department of Agriculture, Dimitri says she wasn’t too surprised to hear about the $7 coffee. “Living in Manhattan,” she says, “people would probably pay even more than that for a cup of coffee.” She sees the launch as a way to appeal to a new set of customers who might have seen Starbucks as selling adequate but not speciality coffee, whether it be for taste or for its unique ethical sourcing, which Starbucks is seeking to expand.

Though Starbucks aims to have all of its coffee meet standards for farmer wages and working conditions by 2015, Dimitri says, “My students tend to be a little bit suspicious of the big companies that enter this area,” as when Walmart began carrying organic products. But Dimitri has a hard time criticizing large companies motives if the end result is an improved livelihood for farmers. Ethical sourcing practices, as defined by Conservation International, include provisions for environmental sustainability as well as economic.

But the commitment is hard to measure. Taking Starbucks as an example, Dimitri says, “You can do a good thing but really a better thing would be for no one to buy coffee in a coffee shop in a disposable cup. Does ethically sourcing some of your coffee, is that sufficient to outweigh all of the garbage that’s created?”

The impact of climate change is hard to estimate but the study out of Ethiopia took predictions from the Intergovernmental Panel on Climate Change to ask what would happen to Arabica bean crops if the temperature increased within a range of 1.8° C  to 4° C.

The potential losses would not only mean more expensive coffee for consumers, but fewer jobs and less economic stability for producers. According to the report, “total coffee sector employment [is] estimated at about 26 million people in 52 producing countries.” The study also reports that coffee is the second most traded commodity after oil.

In another alarm-sounding report from the World Bank, the development agency writes that though global food prices have fallen from a peak in July, “prices remain at high levels – 7 percent higher than a year ago.” Some specific crop prices are much higher still, including maize, which is 17 percent more expensive than it was in October, 2011.

In the case of coffee, Colombia recently announced a plan to offer insurance to growers to protect them from losses incurred from severe weather, according to South Africa’s Times Live.

This World Bank chart maps the current annual rise in sea level due to land-ice melt only, with red being the greatest (around 1.5 mm/year) and blue actually reflecting a drop in sea level. Compare the regions likely to be hardest hit to those that produce the most coffee.

“More people should be thinking about it and talking about it,” says Dimitri. “I don’t think that our policymakers take it as seriously as the researchers do.”

For the consumers who are concerned and have the means and access to purchase sustainably, ethically produced foods, Dimitri says, “they’re willing to make sacrifices in other areas.”

Through a sheer appeal to quality, Starbucks is hoping consumers will find that reason enough to spend on the newest varietal in its Reserve line. Plus, it’s actually not the most expensive cup of coffee ever sold, if you count add-ons. One customer with a veritable blank-check coupon went wild crafting the priciest drink he could, according to Piper Weiss, and topped out at $23.60. His drink–if you can really still call it that–consisted of, “one Java Chip Frappucino ($4.75), plus 16 shots of espresso ($12), a shot of soy milk (.60), a drop of caramel flavoring (.50), a scoop of banana puree ($1), another scoop of strawberry puree (.60), a few vanilla beans(.50), a dash of Matcha powder (.75), some protein powder (.50) and a caramel and mocha drizzle to cap it off (.60).”

Still, for a straight up cup of Joe, it takes the cake. ”It is the highest price we’ve ever had,” a spokesperson told CNBC, adding, “It raises the bar.”

According to the World Bank, EPA, UN and others, that bar doesn’t need much help.

It’s not peanut butter jelly time. In fact, put down the peanut butter and walk away slowly. If the spread you are putting on your morning toast is from a jar of Organic Trader Joe’s Creamy Salted Valencia peanut butter, you may just want to stick with jelly. The reason? The Food and Drug Administration issued a summons to shut down the country’s largest organic peanut butter processor earlier this week, per the Associated Press.

Salmonella in peanut butter is no new discovery—in 2007, contaminated Peter Pan products resulted in 329 reported cases in 41 states—and this past September, Trader Joe’s voluntarily recalled its Creamy Salted Valencia Peanut Butter due to contamination with salmonella thought to be from Sunland, Inc., located in Portales, New Mexico. The outbreak of salmonella poisoning—41 people infected in 20 states—has since been traced to the New Mexico plant, which distributes to major food retailers including Trader Joe’s, Whole Foods and Target. FDA inspections found samples of salmonella in 28 places in the plant—unclean equipment and uncovered trailers of peanuts outside of the factory, too. Not to worry, though, Sunland Inc. hasn’t manufactured peanut butter since the initial voluntary recall in September.

But how does salmonella get into peanut butter in the first place? Dr. Mike Doyle, who has assisted in helping Sunland getting their plants back up and running again and serves as director of the Center for Food Safety at the University of Georgia, explains that peanuts grow in the ground and can be contaminated from a variety of sources: manure, water, wild animals—even the soil. Studies have shown that once present, salmonella can survive for many months—even years—in peanut butter, according to Scientific American. Before treatment, in fact, about two percent of all peanuts are contaminated with salmonella.

“When harvested, we assume there can be some salmonella present and we have to use a treatment to kill it,” Doyle says. A roaster with air temperatures set to about 300 degrees Fahrenheit destroys salmonella in peanuts. For this reason, this moment in the process is often referred to as the “kill step” by manufacturers. The biggest challenge, then, is to prevent contamination in processing plant after the roasting.

“Water is one of the biggest problems in dry food processing for salmonella proliferation,” Doyle says. “If water is available to salmonella, it will grow.”

Dry food manufacturers like a peanut plants or breakfast cereal producers, for example, must minimize the use of water in the plant. Everything from leaks in the roof to the water used to clean up a mess needs to be controlled.

So what can be done to prevent future contamination? There are a variety of things that can be done to upgrade systems and facilities, Doyle says. But all food processors are different in how they control harmful microbes in their plants. As for the Sunland plant, Doyle says they’ve traced the root cause of the contamination to the roaster room.

“The company is in the process of making changes to prevent future contamination,” he says. “They’re gutting the room—new walls, new floors—and fixing other things that need to be addressed.”

What are you really saying to your teacher when you hand over a polished apple on the first day of school? Photo by Flickr user ollesvensson.

The apple, that innocent bud of an Americana autumn, has pulled off one of the greatest cons of all time. As students across the country prepare to greet a new school year and teacher with a polished bit of produce, the apple cements its place in the patriotic foods pantheon despite its dodgy past.

The apple was long associated with the downfall of man, but has managed to do pretty well for itself since. Illustration from Eve’s Diary, written by Mark Twain.

A clever bit of biology, well documented in Michael Pollan’s Botany of Desire, and a tireless cheer campaign of fall orchard visits and doctor-endorsed slogans saved the apple from its bitter beginnings in early America. Though its standing in society today is rivaled only by bald eagles and baseball, the apple’s journey to ubiquity was tumultuous.

Stretching back to the hills of Kazakhstan, early apples were a far cry from today’s sweet, fleshy varieties. As Pollan explains, sweetness is a rarity in nature. Apples benefitted from being bitter and sometimes poisonous because it allowed the seeds to spread unmolested. Because each seed has the genetic content of a radically different tree, the fruit came in countless forms, “from large purplish softballs to knobby green clusters.”

When the apple came to the American colonies, it was still a long way from a sweet treat. Bitter but easy to grow, the produce made excellent hard cider. In a time when water was considered more dangerous than consuming alcohol, hard cider was a daily indulgence. Its distilled cousin, applejack, also became popular, according to documentation from Colonial Williamsburg.

As anyone who grew up in the Ohio River Valley knows, the greatest champion of the fruit was a wandering missionary named John Chapman, or Johnny Appleseed. Pennsylvania, Ohio, Indiana and beyond bloomed in the wake of his visits. He was opposed to grafting, the practice of inserting “a section of a stem with leaf buds is inserted into the stock of a tree” to reproduce the same type of apples from the first tree, as described by the University of Minnesota.

Without the human intervention, however, apples remained overwhelmingly bitter and when an anti-alcohol fervor swept the nation in the late 19th century, the plant’s fate was in peril. One of the fiercest of opponents, temperance supporter and axe-wielding activist Carrie Nation, went after both growers and bars, leaving a wake of destruction in her path. Nation was arrested 30 times in a ten-year span for vandalism in the name of her movement, according to PBS.

“But with the help of early public relations pioneers crafting slogans such as “an apple a day keeps the doctor away,” the plant quickly reinvented itself as a healthy foodstuff,” according to the PBS production of Pollan’s work.

Elizabeth Mary Wright’s 1913 book, Rustic Speech and Folk-lore, recorded the use of apples as part of common kitchen cures. “For example,” she writes, “Ait a happle avore gwain to bed, An’ you’ll make the doctor beg his bread…or as the more popular version runs: An apple a day Keeps the doctor away.”

Free to produce a socially acceptable fruit, growers raced to develop sweet, edible varieties that would replace the plant’s previous life. Shaking its association with hard cider and reckless imbibing, the apple found a place in one of the most faultless places of American society: the schoolhouse.

Held up as the paragon of moral fastidiousness, teachers, particularly on the frontier, frequently received sustenance from their pupils. “Families whose children attended schools were often responsible for housing and feeding frontier teachers,” according to a PBS special, titled “Frontier House, Frontier Life.” An apple could show appreciation for a teacher sometimes in charge of more than 50 students.

Apples continued to be a favorite way to curry favor even after the practical purpose of feeding teachers disappeared. Bing Crosby’s 1939 “An Apple for the Teacher,” explains the persuasive allure of the fruit. “An apple for the teacher will always do the trick,” sings Crosby, “when you don’t know your lesson in arithmetic.”

By the time American scholar Jan Harold Brunvand published his book, The Study of American Folklore, in 1968, the phrase “apple-polisher” was more or less shorthand for brown-nosing suck-up. With cutting-edge technology in classrooms seen as an academic advantage, many teachers may be asking for a completely different kind of apple: not a Red Delicious or Granny Smith but an iPad.

Soak grain in water and a seed begins to sprout. Dry out that tiny protoplant, or acrospire, roast it, and you’ve got malt—the basis for fermenting beer (and distilling whiskey too). The process can be crude; soaking can take place in a puddle, drying on the roof of a house. I wrote about the small-scale revival of the malting process, of the more modern variety, in The New York Times last week and it’s curious just how far the process predates the current garage-scale renaissance, the flourishing of regional malthouses in the 19th century, or even the English maltsters who first set up shop on American soil four hundred years ago.

The late historian Peter Damerow, of the Max Planck Institute in Germany, published an examination of 4,000-year-old cuneiform writings found near present day Turkey, including a mythic text from ancient Sumerian tablet known as the “Hymn to Ninkasi.” Ninkasi was the goddess of brewing. In the paper, published earlier this year, he explains that the hymn accompanied “a kind of drinking song” dedicated to a female tavern-keeper. It’s the first recipe, of sorts, for beer:

Ninkasi, you are the one who handles dough (and) … with a big shovel,
Mixing, in a pit, the bappir with sweet aromatics.
Ninkasi, you are the one who bakes the bappir in the big oven,
Puts in order the piles of hulled grain.
Ninkasi, you are the one who waters the earth-covered malt (“munu”),
The noble dogs guard (it even) from the potentates.
Ninkasi, you are the one who soaks the malt (“sun”) in a jar,
The waves rise, the waves fall.
Ninkasi, you are the one who spreads the cooked mash (“ti-tab”) on large reed mats,
Coolness overcomes …
Ninkasi, you are the one who holds with both hands the great sweetwort (“dida”),
Brewing (it) with honey (and) wine.
Ninkasi, [...]
[You ...] the sweetwort (“dida”) to the vessel.
The fermenting vat, which makes a pleasant sound,
You place appropriately on (top of) a large collector vat (“laÌtan”).
Ninkasi, you are the one who pours out the filtered beer of the collector vat,
It is (like) the onrush of the Tigris and the Euphrates.

As archeologist Patrick McGovern has written in Uncorking the Past, the domestication of barley in the Fertile Crescent led to the emergence of a forebear to modern beer some 6,000 year ago, providing a possible motive for a decisive step in the development of human culture and the so-called Neolithic Revolution. Beer may have come before bread. Still, these cuniform tablets are notoriously difficult to translate and leave only a rough outline of the process—so, despite the best efforts to replicate the Tigris-like rush of ancient Sumerian beer today, unanswerable questions about the beer’s exact composition remain. When, for example, did they interrupt the germination of the “earth-covered” malt, a crucial step enabling a grain to undergo alcoholic fermentation?

Damerow suggests there’s reason to doubt whether these brews even proved to be much of an intoxicant 4,000 years ago: “Given our limited knowledge about the Sumerian brewing processes, we cannot say for sure whether their end product even contained alcohol.” Then again, would we really have kept the ancient process alive for so long if it just gave us better nutrition and didn’t also make us feel good?

Milk does the body good. It’s the instructive stuff of life; compounds in a mother’s milk can instill lifelong flavor preferences in her breast-fed offspring. (Meanwhile, infants fed cow’s milk formula may gain excessive weight.) Raw milk enthusiasts claim that cow’s milk is more beneficial if it hasn’t been heated and pasteurized. If Dana Goodyear’s recent story in The New Yorker (subscription required) is any indication, this vocal minority’s claims about a milky unpasteurized panacea is increasingly getting mainstream attention.

The raw milk trend has a certain appeal among libertarians, such as Ron Paul, who view the fight against food regulation as a symbol of freedom. But what’s curious about this movement is that Goodyear (and presumably The New Yorker’s estimable fact-checkers) found only one scientific study to support claims about the immune-enhancing properties of raw milk: the GABRIELA study, a survey conducted in rural Germany, Austria and Switzerland and published in October 2011 in the Journal of Allergy and Clinical Immunology. The study’s authors found that unheated “farm milk” contained a protective protein, although it could only partly explain the reduced rates of asthma. Raw milk might be one variable in a web of confounding factors. (After all, the children lived in rural homes, not in sterile labs.) The authors found no association between the bacterial counts in milk and a child’s health; they also couldn’t say whether those samples were representative of a child’s long-term exposure, nor could they rule out the effects of microbial exposure on a child’s developing immune system.

Perhaps raw milk represents a subset of post-Pasteurian activism opposed to our culture’s blanket war on germs. Since about 1989, when David Strachan advanced the “hygiene hypothesis,” an increasing body of evidence links chronic underexposure to germs and microbes to lasting health consequences. The idea is that encountering low levels of nonthreatening stimuli trains our bodies to fight potential allergens and, without such exposure, our immune systems malfunction. Just last week, a group linked the lack of biodiversity in urban areas for a “global megatrend” in allergies and chronic inflammatory diseases.

The health benefit of raw milk remains speculative and its risks remain high—milk is an excellent medium for the growth of pathogenic bacteria. But the GABRIELA study may hint at something else: the health halo of a nostalgic, if apocryphal, place. What little scientific research there is came from the Alps—a sort of Hunza Valley of the West—a place seemingly removed from the ills of modern society, home to Heidi and the curative powers of her grandfather’s goat’s milk (an idea in Nathaneal Johnson’s blog and forthcoming book, The Heidi Hypothesis). Then again, when has the quest for pure, natural foods really hinged on rational arguments?

Long before hops plants form their long, sticky cones, the plants send up a little shoot. I picked a handful of these shoots from my dad’s hop bines last week (yes, they’re called bines, not vines). While no international price index charts the prices of vegetables, hop shoots are considered among the world’s most expensive vegetables, commanding a far higher price than prized white asparagus. (This back-of-the-envelope calculation excludes saffron, which is a crocus stigma and not a “vegetable” per se; the other contender, white truffles, are fungi.)

Hops, the bittering agent in most beers, is one of two common commercial species in the cannabaceae family—ironically, the one of lesser value. Unlike the other, marijuana, hops are considered legal and their shoots edible. In Belgium, these hopscheuten are cultivated under glass or in dark rooms, since the shoot turns green and develops a harder, rope-like consistency when it emerges outdoors.

In Elizabeth David’s 1969 essay “Bruscandoli,” collected in An Omelette and a Glass of Wine, she writes about the fleeting pleasure of Italian risotto and frittata made with hop shoots, which also go by the names wild asparagus, bruscandoli, luppoli and jets de houblon. “Because they were so very much there one day and and vanished the next,” she writes, “bruscandoli became a very sharp and poignant memory.”

After hop plants become established, it’s necessary to thin their bines. A few years ago, in 2009, I called Puterbaugh Farms, a hops grower in Washington that pickles hop shoots in much the same way you’d make dilly beans. “We go out and trim the hop shoots in the spring,” Diana Puterbaugh told me. “I guess you call it a waste product.”

What’s curious is that the use of hops as a mildly bitter spring green predates hopped beers, the first record of which dates to around 822 A.D. Nearly 800 years earlier, Pliny the Elder said Italians ate the wild Lupus salictarius, although he wrote, “these may be rather termed amusements for the botanist than articles of food.”

Douglas Gayeton, the author of Slow: Life in a Tuscan Town, has been exploring the principles of sustainability through photography, taking abstract concepts and turning them into annotated infographics—or “information art.” It’s part an ongoing series called The Lexicon of Sustainability.

The images convey invisible or purposely obfuscated ideas related to food, and the concepts are explained by the experts themselves, like Elaine Ingham (above) translating soil science and microbiology for the masses. Paul Stamens (in the photo below) explains the concept of myco-remediation. I talked with Gayeton about the project from his home in Petaluma, California.

How did you come up with the concept and what do you hope these images will convey?

Images often leave you asking more questions than providing answers. When I see a photo, what I want to know is not always explained. So, I thought to myself, “Wouldn’t it be great if I could include an image and then include all the things that you’d want to know if you were looking at the image?” I began to make images and have people talk about them, essentially describing what’s happening. I really wanted to demystify the language of sustainability.

The process—information art—takes complicated ideas and makes them simple to understand. The Lexicon Project started with food and farming and now it’s looking at climate change and water. We’re starting to get into technical exploration of ideas. It’s almost a formula—in much the same the way in physics that you create a formula to describe an activity or an action in the physical world. That formulaic approach your see—used in physics or math—is the same type of construction that I use for the images. More than a construction actually, these images are a deconstruction of ideas, reducing them to their essence, then trying to find a way to graphically represent them. Somebody once wrote that one of the interesting thing about the work is that it works the way a mind works: If I were to simply give you a piece of paper with a lot of writing on it, you might skim over it; but if I were to take a bunch of ideas and place them on an image, then you are suddenly active in the idea. You’re active in the appreciation of the idea. That activity creates a narrative and makes it easier to retain information. You have more of a deeper connection…. It’s not a passive experience. The active experience of turning the reading of something into it’s almost a game-like quality, I think it allows people to connect more intimately with the ideas and images.

Douglas Gayeton is planning 500 pop-up shows this summer, and anyone can be apply to be curator here.

Artisanal baker Eli Rogosa. Photo by Amy Toensing

The December issue of Smithsonian magazine features a story about heirloom wheat and the people who grow and bake with it. Eli Rogosa, director of the Heritage Wheat Conservancy and an artisanal baker, talks about her work in the field and in the kitchen. At the end she shares her recipe for a heritage bread.

Q: Why did you decide to devote your time to heritage varieties of wheat?

A: The silent crisis of the loss of genetic diversity of one of the world’s staple food crops is very serious—and very exciting, because there are still a lot of varieties that are in gene banks.

Q: What is your most memorable experience baking?

A: I’m working with a species of grain called einkorn, which is getting a lot of publicity these days because it’s safe for those with gluten allergies. Einkorn was originally domesticated in the Tigris/Euphrates/ancient Mesopotamian region, which today is Iraq. So I went down to the local Iraqi bakery recently and I said, “Would you like to try this bread in your bakery?” They were really excited, so I brought them some einkorn flour and they baked traditional Iraqi flatbread. They just couldn’t believe it. They said, “This is real bread, this is what it’s supposed to taste like.” The traditional methods that they bake with were the ways that einkorn was baked with for millennia. Now I think there’s five halal stores in the city where I was, Portland Maine. They just want to buy einkorn, so it’s in all the stores.

Q: Are there differences between working with flour milled from heritage wheats and standard supermarket flour?

A: It’s a whole different ballgame to buy from a local wheat grower rather than to buy from the store. The modern wheats are completely uniform. If you buy something from the supermarket, you know exactly what to expect. But if you buy a local variety from a local grower, it’s going to reflect the fertility, the variety, the weather. That explains why breads from different countries are so different.

Q: Can you substitute flour made from heritage grains for supermarket flour?

A: You can substitute. You probably might need a little less water, a little more salt because it’s lower gluten. But I just bake bread normally. I bake bread in the morning for my husband. Instead of doing a lot of kneading, I make my dough the night before and just let it sit and it gets a little bit fermented, like a light sourdough. So I think time is a factor if you make your dough the night before and then bake it the next day. It’s really easy.

Q: How much experimentation does it take before you get a bread recipe just right?

A: I don’t use recipes. I’m a creative baker—it’s easy to bake. I’ve read all the books, but I didn’t learn baking from books; I learned it from illiterate grandmas in Third World countries. Baking is like a natural process. You feel when it works right and follow the dough, and it’s very liberating when you bake by feel and consistency of the dough and not measuring. You have to play around to feel comfortable and familiar with what works.

Q: What advice would you offer to someone interested in growing heritage wheats in his or her own back yard?

A: Find a local source for heritage wheat seeds, or contact me at growseed.org, and I’ll send you samples. It’s easy. Wheats are a grass. It’s the easiest crop I’ve grown on our farm. I grow only winter wheat, which means I plant it in September and harvest in July. I find that the winter wheats are better adapted, and in the spring they just shoot up and they compete with weeds, so your weeding pressure is really decreased.

Recipe for einkorn sprout bread, by Eli Gogosa

(Makes two loaves)

STEP 1: ADVANCE PREPARATION

Five days before baking, mix 1 tablespoon (T) non-chlorinated water (spring water, distilled water, well water or rain water, NOT tap water) with 1 T einkorn flour in a bowl. (Both einkorn flour and einkorn grain are available at natural foods stores or from growseed.org. Optional: Add 1 T cultured butter milk to encourage fermentation.) Cover but don’t refrigerate. Each following day, mix in another 1 T einkorn flour and 1 T non-chlorinated water.  Keep the bowl at room temperature until the mixture has started to bubble. This is sourdough starter. Two days before baking, soak 1 cup einkorn grain in the non-chlorinated water overnight in a covered bowl. The next day pour off the water. Rinse daily and keep covered. The grains might start sprouting rootlets.

STEP 2: MAKING THE BREAD DOUGH

In a food processor, blender or hand-crank food mill, blend the soaked grains briefly so they are the consistency of chunky oatmeal. Mix the starter, 1 cup blended grain and 4 cups einkorn flour, 1 teaspoon (t) sea salt and 1 3/4 cups warm water. (If you are concerned that you may not have sufficient starter, add 1 t yeast. Optional: For sweeter, festive bread, add some chopped dates and walnuts to taste and 1/2 cup maple syrup in place of 1/2 cup water.) Add more flour if the dough is too sticky or more water if too dry. Knead the dough until it forms a ball that springs back when you poke it. Shape the dough into two loaves—flatbreads, boules or standard bread-pan loaves. Refrigerate overnight in bread pans or on a baking sheet greased with olive oil and dusted with einkorn flour.

STEP 3: BAKING

The next day, let the two loaves warm to room temperature for 1/2 hour. Dust the surfaces of the loaves with einkorn flour. Slash if desired. Preheat the oven to 400 degrees. Turn down the oven to 350 degrees. Bake the loaves at 350 degrees for 45 minutes or until the tops of the crusts are golden brown. Turn the oven off, but keep the loaves inside for another 1/2 hour before taking them out.
