In 1994, Julie Languille lived at the epicenter of the Northridge earthquake, which struck the Los Angeles neighborhood with a magnitude of 6.7. She and her family were without power for two weeks, and the long lines at nearby grocery stores soon began to shrink as food ran out.

“It just became really important to me as part of my feeling of security and good planning for my family to have meals on hand,” Languille says.

The Puget Sound resident, who also runs a dinner planning website, has been canning meals since, and her recipes, ranging from oatmeal and macaroni and cheese to braised chicken and pulled pork, are featured in a cookbook published next month. Two years ago, Languille installed a full-scale food storage unit in her home, filling it with almost 100 jars of basic ingredients like meats and veggies to complex ready-made recipes for baby back ribs and chicken noodle soup. Besides canning and sealing tools, an assortment of jars and enough room in the kitchen, the only other ingredients necessary are water and some heat.

In her cookbook, Languille writes that her bags, jars, and boxes of shelf-stable meals are “insurance against hardship or hunger.” Aside from earthquakes and hurricanes, ready-made meals significantly cut prep time for dinner on a busy weeknight. No washing, cutting, chopping and measuring—that was done weeks or months ago. Jars contain 100 percent of the ingredients necessary (other than water) for any given recipe, which nixes an extra trip to the grocery store for a forgotten item.

When stored in a cool, dry and dark place, dry meals can last for decades. Almost every fruit or vegetable can be dehydrated, a 24-hour process at high temperatures, and freeze-dried meats, which Languille says she buys online, have a long shelf life. But does the flavor of the ingredients hold up?

Languille says the answer is yes. When water is added, powdered eggs transform into fluffy beaten eggs and sour cream powder into dollops of the real stuff. Dehydrated apples, peaches and plums turn into gooey cobbler filling in the oven. Ground beef, once browned in a skillet and pressure-canned in a sterile jar for 75 minutes, becomes hearty chili when deposited into a pot of boiling water.

“The meals that I have on hand are tastier than the commercially prepared dried foods,” says Languille, who doesn’t use any artificial flavoring, coloring or preservatives in her recipes, save for a few packets of oxygen absorbers, which keep food from changing color or growing mold.

Languille replenishes her inventory four times a year, churning out nearly 40 canned jars in one weekend after a Costco-sized shopping trip. Whole meals are stored in quart-size jars and can produce soups and stews for parties of six to eight. Hamburger meat and chicken go in pint-size jars, which hold about a pound of meat and can serve four people

Languille uses a vacuum sealer to suck the air out of pouches filled with food. A dehydrator sucks out moisture from meats and vegetables, reducing their water content so they won’t spoil. A pressure canner preserves low-acid foods like meats, beans and vegetables.

Canning works in two ways. Pressure canning is used to preserve low-acid foods like meats, beans and vegetables. For example, a jar containing a piece of chicken is placed inside a pressure canner, which increases the pressure of the contents, causing steam to push out all of the air trapped inside. Then, the chicken remains stable at room temperature for long periods of time.

Water bath canning is used to preserve high-acid foods like fruits and tomatoes. Food is stored in sterilized jars, topped with warmed lids, and then boiled. This method works well for making jams and fruit butters and preserving spaghetti sauce and salsas

Canned and dry ingredients are packaged together in many of Languille’s recipes. Meat and sauce are cooked and canned together, then tossed into a jar with a sealed bag of pasta sauce and placed in a cupboard. Chicken canned with vegetables can be packaged with noodles to make chicken noodle soup or paired with flour and pie crust ingredients to produce a chicken pot pie.

Read on for the recipe for chicken noodle soup, which Languille says is her favorite, and others, featured in her forthcoming cookbook “Meals in a Jar: Quick and Easy, Just-Add-Water, Homemade Recipes.”

Chicken Noodle Soup
Makes 8 servings

For soup mix: In each of 8 quart-size canning jars or retort pouches, add, seal, and then pressure-can for 75 minutes:
• 1 cup chopped lightly browned chicken
• ¾ cup chopped onion
• ¾ cup peeled and chopped carrots
• ¾ cup chopped celery
• 2 tablespoons chicken soup stock
• 1 slice dehydrated lemon
• 2 teaspoons dried thyme
• 1 bay leaf
• Water, to cover and leave 1 inch of headspace in a 1-quart jar, or 2 inches in a retort pouch

For noodle packet: In each of 8 vacuum bags, add and then seal:
• 2 cups egg noodles

In each of 8 Mylar bags, tote bags, or vacuum bags, store:
• 1-quart jar or retort pouch chicken soup mix
• 1 packet noodles

Combine the chicken soup mix and 12 cups of water in a large pot over medium heat. Bring to a simmer and add the noodles. Simmer for about 10 minutes, or until the noodles are tender. Remove the bay leaf and lemon slice, and serve.

Omelet in a Bag
Makes 16 (2 to 3-serving) meals

In each of 16 zip-top quart-size freezer bags, package:
• ¼ cup powdered eggs
• 1 tablespoon finely grated Parmesan cheese
• 1 teaspoon dried chives or thyme
• ¼ teaspoon salt
• 1 pinch pepper

Heat a medium pot of water over medium heat to just simmering. Add ¹⁄₃ cup of water to the bag and squish the bag to combine (or put in a bowl and stir with a fork). Place the bag of omelet mixture into the water and simmer 10 to 15 minutes, until solid and just cooked through. Divide the omelet into portions and serve.

Peanut Butter Cookies
Makes 6 batches (about 3 dozen cookies each)

For cookie mix: In each of 6 vacuum bags, Mylar bags, or jars, add and then seal:
• ½ cup granulated sugar
• ½ cup brown sugar
• 1 tablespoon powdered eggs
• 1¼ cups flour
• ¾ teaspoons baking soda
• ½ teaspoon baking powder
• ¼ teaspoon salt

For peanut butter: In each of 6 vacuum bags or disposable 4-ounce containers, add and then seal:
• ½ cup (4 ounces) peanut butter

For shortening: In each of 6 vacuum bags, add and then seal:
• ½ cup shortening

In a Mylar bag, tote bag, or vacuum bag, store:
• 1 jar or pouch cookie mix
• 1 packet peanut butter
• 1 packet shortening

Preheat the oven to 375°F. In a large bowl, combine the shortening, cookie mix, and 2 tablespoons of water until a stiff dough forms. Roll into small balls about the size of walnuts and flatten with a fork in a crisscross pattern. Place on a baking sheet about 2 inches apart. Bake for 10 to 12 minutes or until lightly brown.

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.”

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.

In 2007, the Naga Bhut Joloki or “Ghost chile” was named the hottest pepper on earth. Then in 2010 the Naga Viper stole the title. And in 2012 the Trinidad Scorpion Moruga Blend moved into the lead. And for good reason.

The Scorpion ranks at round 2 million heat units on the Scoville scale. (For comparison, tabasco sauce has 2,500–5,000 Scoville heat units or SHU.) What exactly does that mean? When the scale was invented in 1912 by pharmacist Wilbur Scoville in search of a heat-producing ointment, it was based on human taste buds. The idea was to dilute an alcohol-based extract made with the given pepper until it no longer tasted hot to a group of taste testers. The degree of dilution translates to the SHU. In other words, according to the Scoville scale, you would need as many as 5,000 cups of water to dilute 1 cup of tobacco sauce enough to no longer taste the heat.

And while the Scoville scale is still widely used, says Dr. Paul Bosland, professor of horticulture at New Mexico State University and author or several books on chile peppers, it no longer relies on the fallible human taste bud.

“It’s easy to get what’s called taster’s fatigue,” says Bosland. “Pretty soon your receptors are worn out or overused, and you can’t taste anymore. So over the years, we’ve devised a system where we used what’s called high performance liquid chromatography.”

That’s a fancy way of saying that scientists are now able to determine how many parts per million of heat-causing alkaloids are present in a given chile pepper. The same scientists have also figured out that if they multiply that number by 16, they’ll arrive at the pepper’s Scoville rating (or “close enough for the industry,” says Bosland).

And, let’s face it, who would want to be the one to taste test a pepper named after a viper or a scorpion? Or maybe the better question is what sane person would? The BBC recently reported on the first man to finish an entire portion of a curry made with ghost chiles, called “The Widower,” and he suffered actual hallucinations due to the heat. Bosland told the AP in 2007 he thought the ghost chile had been given it’s name “because the chili is so hot, you give up the ghost when you eat it.” How’s that for inviting?

Indeed, the capsaicin, the spicy chemical compound found in chiles demands the diner’s attention much like actual heat heat does. And it turns out there’s science behind that similarity. “The same receptor that says ‘hot coffee’ to your brain is telling you ‘hot chile peppers,’” says Bosland.

And what about the rumor that very hot peppers have the potential to damage our taste buds? Not true. Bosland says we should think of chile heat like we do the taste of salt; easy to overdo in the moment, but not damaging to your mouth over the long term. Even the hottest habanero (100,000–350,000 on the Scoville scale), which can stay on your palate for hours — if not days –  won’t wear out your tender buds.

Bosland and his colleagues have broken the heat profile of chile peppers into five distinctly different characteristics. 1) how hot it is, 2) how fast the heat comes on, 3) whether it linger or dissipates quickly, 4) where you sense the heat – on the tip of tongue, at the back of throat, etc., and 5) whether the heat registers as “flat” or “sharp.”

This last characteristic is fascinating for what it says about cultural chile pepper preferences (say that five times fast). Apparently those raised in Asian cultures — where chile heat has been considered one of the six core tastes for thousands of years — prefer sharp heat that feels like pinpricks but dissipates quickly. Most Americans, on the other hand, like a flat, sustained heat that feels almost like it’s been painted on with a brush.

The Chile Pepper Institute, which is affiliated with New Mexico State University, sells a nifty chile tasting wheel, which describes the heat and flavor profiles of many different chiles and offers advise on how to cook them.

Eating chiles is a little like tasting wine, says Bosland. “When you first drink wine, all you notice is the alcohol. Then you can tell red from white, and soon you can taste the difference between the varietals. Eventually you can tell what region the wine comes from. That’s how it is with chile peppers too. At first all you taste is heat, but soon you’re be able to tell which heat sensations you like best.”

I love decorating my apartment for the holidays. The day after Thanksgiving, the tree goes up and it—along with windows and tables and other flat surfaces I can do without for the next four to six weeks—are festooned with whatever seasonal odds and ends I’ve amassed over the years. Not sure what it is, but when I walk into my home at night and am greeted by scads of novelty lighting, I suddenly feel at peace with the world. In recent years, I’ve indulged my love for shabby chic (or maybe just campy) decor by making beer can reindeer, which I’m currently using to decorate the living room shelf used to house bottles of my preferred adult beverages. (It’s a theme. I’ll work it for all it’s worth.) But as I began to look at the decorations in my apartment, and ponder how the halls were decked in past Christmases, it occurred to me that there are lots of ways to use goods in the pantry to make your digs a little merrier. Here are a few ideas for the foodie who has yet to trim their home:

Popcorn and/or Cranberries: When I think of garland, my mind immediately gravitates to the metallic boas used to wrap around bannisters and trees—maybe even a younger sibling. But you can also make your own—and from products that will actually biodegrade. One option is to make a garland out of popcorn: buy yourself a bag of popcorn (not the kind you microwave), prepare and, using a needle threaded with waxed dental floss, string on as many fluffy white kernels as your heart desires. When you’re through with the garland, set it outside for the birds. You can also use fresh cranberries. The fruit should dry nicely on the tree and keep for a few weeks; however, be careful about placing fruited garlands on surfaces that might stain. Alternate cranberries and popcorn, or, as Better Homes and Gardens suggests, add slices of lime for a festive splash of green. Some people spray their garlands with shellac so they can be used a little longer; however, if you do, please do not leave these outside for the animals to eat.

Gingerbread: How could you complain about edible ornaments for your tree? Martha Stewart has recipes for gingerbread that will be strong enough to be used as decoration, but not so tough that you can’t enjoy the fruits of your labors. Roll out a tray of gingerbread people, remembering to make a hole so you can string through a length of ribbon. Bake, decorate and hang. The cookies need to set up overnight, but I also wouldn’t let them stay on the tree but for so long. Stored in airtight containers, they keep for a week—so when out in the open, you have a much more limited time frame to eat them. This might be something you want to do a day or two before Christmas. What could be nicer than waking up on the 25th, gathering around the tree and having cookies to dunk in your coffee? You can also make a gingerbread house, which some people eat at the end of the season, but others spray it with a coat of shellac and use it for several years.

Dough: Another classic option is to whip up a batch of ornament dough. Nothing but flour, salt and water, I suppose this is technically edible while raw (not that I’d recommend that), but because you can make it with items you can find in your kitchen, I’m including it on this list. Roll out the dough and make festive cutouts, bake off and decorate with paints, glitter and any other craft trimmings you like. If you’re a Michelangelo in training, sculpt figures—but remember that the back side is going to be resting on a baking sheet and will be completely flat. You can back those ornaments with colored felt to pretty up the undecorated side after they’re baked and cooled. And before baking, don’t forget to make a hole where you want your ornament hanger to go.

Cinnamon: If you have an abundance of cinnamon sticks in your pantry and you’ve no idea how to use them, I strongly suggest making yourself cinnamon stick Santas. Aside from the cinnamon, you just need some acrylic paint to render the facial features and a product called Sno-Tex (also sold under the name snow paint) to create a textured white beard. Attach a ribbon and hang on your tree.

Peppermint: I love wreaths. Between the splash of color and, if you’re using live botanicals, an invitingly aromatic way to greet your holiday visitors at the door. You can also greet your guests at the door with food by crafting a wreath using star mints. For this, you need a coat hanger or metal hoop, bags of mints or other hard candy with the cellophane tails, and embroidery thread. If using a coat hanger, shape the hanger into a circle and begin tying candies onto your wreath form until you have a full wreath. Top with a bow, and you’re good to go. If you’re using candies with cellophane tails on both ends, your guests will have a tail to tug on to get at a holiday treat. If you’re using hard candies with a tail on just one end, consider attaching a small pair of scissors to your wreath with a strand of ribbon or yarn so your guests can easily snip off their candy.

As our regular readers may know, we like our “five ways” posts so I’m cutting it off here. But I’m sure there are lots more ways to work food into holiday home decor. Let us know in the comments section below how you get crafty with food to make the season a little brighter in your home.
