The Science Behind Brining Your Thanksgiving Turkey

At many Thanksgiving tables, the annual roast turkey is just a vehicle for buttery mash and creamy gravy. But for those who prefer their bird be a main course that can stand on its own without accoutrements, brining is an essential prep step—despite the fact that it requires finding enough room in the fridges to immerse a 20-pound animal in gallons of salt water for days on end. To legions of brining believers, the resulting moist bird is worth the trouble.

How, exactly, does a salty soak yield juicy meat? And what about all the claims from a contingency of dry brine enthusiasts: Will merely rubbing your bird with salt give better results than a wet plunge? For a look at the science behind each process, we tracked down a couple of experts.

First, it's helpful to know why a cooked turkey might turn out dry to begin with. As David Yanisko, a culinary arts professor at the State University of New York at Cobleskill, tells Mental Floss, "Meat is basically made of bundles of muscle fibers wrapped in more muscle fibers. As they cook, they squeeze together and force moisture out," as if you were wringing a wet sock. Hence the incredibly simple equation: less moisture means more dryness. And since the converse is also true, this is where brining comes in.

Your basic brine consists of salt dissolved in water. How much salt doesn't much matter for the moistening process; its quantity only makes your meat and drippings more or less salty. When you immerse your turkey in brine—Ryan Cox, an animal science professor at the University of Minnesota, quaintly calls it a "pickling cover"—you start a process called diffusion. In diffusion, salt moves from the place of its highest concentration to the place where it's less concentrated: from the brine into the turkey.

Salt is an ionic compound—its sodium molecules have a positive charge and its chloride molecules have a negative charge, but they stick together anyway. As the brine penetrates the bird, those salt molecules meet both positively and negatively charged protein molecules in the meat, causing the meat proteins to scatter. Their rearrangement "makes more space between the muscle fibers," Cox tells Mental Floss. "That gives us a broader, more open sponge for water to move into."

The salt also dissolves some of the proteins, which, according to the book Cook's Science by the editors of Cook's Illustrated, creates "a gel that can hold onto even more water." Juiciness, here we come!

There's a catch, though. Brined turkey may be moist, but it can also taste bland—infusing it with salt water is still introducing, well, water, which is a serious flavor diluter. This is where we cue the dry briners. They claim that using salt without water both adds moisture and enhances flavor: win-win.

In dry brining, you rub the surface of the turkey with salt and let it sit in a cold place for a few days. Some salt penetrates the meat as it sits—with both dry and wet brining, Cox says this happens at a rate of about 1 inch per week. But in this process, the salt is effective mostly because of osmosis, and that magic occurs in the oven.

"As the turkey cooks, the [contracting] proteins force the liquid out—what would normally be your pan drippings," Yanisko says. The liquid mixes with the salt, both get absorbed or reabsorbed into the turkey and, just as with wet brining, the salt disperses the proteins to make more room for the liquid. Only this time the liquid is meat juices instead of water. Moistness and flavor ensue.

Still, Yanisko admits that he personally sticks with wet brining—"It’s tradition!" His recommended ratio of 1-1/2 cups of kosher salt (which has no added iodine to gunk up the taste) to 1 gallon of water gives off pan drippings too salty for gravy, though, so he makes that separately. Cox also prefers wet brining, but he supplements it with the advanced, expert's addition of injecting some of the solution right into the turkey for what he calls "good dispersal." He likes to use 1-1/2 percent of salt per weight of the bird (the ratio of salt to water doesn't matter), which he says won't overpower the delicate turkey flavor.

Both pros also say tossing some sugar into your brine can help balance flavors—but don't bother with other spices. "Salt and sugar are water soluble," Cox says. "Things like pepper are fat soluble so they won't dissolve in water," meaning their taste will be lost.

But no matter which bird or what method you choose, make sure you don't roast past an internal temperature of 165˚F. Because no brine can save an overcooked turkey.

The Fascinating History Behind Why Jewish Families Eat Chinese Food on Christmas

For Jewish New Yorkers, scoring a seat at one of veteran restaurateur Ed Schoenfeld’s Chinese eateries on Christmas Day could be compared to a holiday miracle. “I think on that day we do more business than many restaurants do in three months,” Schoenfeld tells Mental Floss. “We serve all day long, we stay open all day long.”

Schoenfeld is the Jewish owner-operator of RedFarm, an Asian-fusion dim sum restaurant with two locations in New York (plus one in London), and Decoy, a West Village shrine to traditional Peking duck. While his expertise lies in Far Eastern cuisine, Schoenfeld grew up in Brooklyn and learned to cook from his Eastern European grandmother. And just like his customers, Schoenfeld and his family sometimes craved Chinese food on Christmas, eschewing homemade fare for heaping plates of chow mein and egg foo yung. The future restaurateur's grandmother kept a kosher kitchen, but outside the home all dietary laws flew out the window with the single spin of a Lazy Susan. Suddenly, egg rolls with pork were fair game, transfigured into permissible delicacies through hunger and willful ignorance.

As Gentiles feast on turkey and roast beef during the Yuletide season, why do many Jews opt for chop suey? For starters, it's convenient: Chinese restaurants are open on Christmas Eve and Christmas Day. But as historians and culinary experts tell Mental Floss, other ingredients play a part in this delicious story.

Jews developed their love for all things steamed, stir-fried, and soy-sauced after leaving the Old Country. Between the mid-1800s and the 1930s, waves of Jewish immigrants from Eastern Europe, Germany, and Greece began settling in Manhattan’s Lower East Side, a gritty, inexpensive neighborhood teeming with tenements, docks, and factories—and filled with synagogues and kosher butcher shops. “You started here, and then moved on," Sarah Lohman, author of Eight Flavors: The Untold Story of American Cuisine, says.

While Jewish immigrants found community on the Lower East Side, "there was a lot of discrimination against Jews at the turn of the century,” Lohman adds. "They were often criticized not only for not dressing like Americans and not speaking the language, but also for not converting to an 'American' religion."

Right next door to the burgeoning Jewish community on the Lower East Side was the city's nascent Chinatown. Many Chinese immigrants had initially come to the U.S. to work on the Transcontinental Railroad. After its completion in 1869, these laborers faced violence and discrimination in the western states. They came to New York City seeking new business opportunities, and some opened restaurants.

By and large, Chinese restaurateurs didn’t discriminate against Jewish customers. Joshua Eli Plaut writes in his book A Kosher Christmas: 'Tis the Season to be Jewish that the Chinese, as non-Christians, didn't perceive any difference between Anglo-Saxon New Yorkers and Jewish immigrants; they accepted all non-Chinese customers with open arms.

Jewish customers embraced Chinese food in return. The restaurants were conveniently located and inexpensive, yet were also urbane in their eyes. Jews saw dining out as an American custom that they wanted to try, largely because they sought upward mobility among other Americans. According to Yong Chen, a history professor and author of Chop Suey, USA: The Story of Chinese Food in America, "[Diners] were attracted to Chinese food because, in their mind, it represented American cosmopolitanism and middle class status." And they weren't deterred by the fact that food in Chinese restaurants wasn't kosher. But they could easily pretend it was.

Dairy wasn’t a big part of Chinese meals, so Jewish diners didn’t have to worry about mixing meat and milk (a no-no in kosher diets). And non-kosher ingredients like pork or seafood were often finely chopped, drowned in sauces, or mixed with other ingredients, like rice. These elements were well disguised enough that they could pass for more permissible forms of meat. “You could kind of willfully ignore that there might be pork in there," Lohman says. "It’s like a vegetarian eating a soup that has chicken stock. If you’re a little flexible about your Judaism, you would just ‘not notice’ the pork in your fried rice.”

Chinese food was exotic and new, filled with surprising flavors, ingredients, and textures [PDF]. But for some Eastern European Jews, it also had familiar elements. Both Eastern European and Chinese cuisines shared an affinity for sweet and sour flavors and egg-based dishes. "[Chinese restaurants] had these pancakes, which were like blintzes,” says Joan Nathan, author of King Solomon's Table: A Culinary Exploration of Jewish Cooking from Around the World, and the wontons resembled kreplach (both are meat-filled soup dumplings).

The fact that the Chinese and Jews were America’s two largest non-Christian immigrant populations brought them together, Jennifer 8. Lee, author of The Fortune Cookie Chronicles: Adventures in the World of Chinese Food, tells Mental Floss. Unlike, say, Italian restaurants, Chinese restaurants were open on Sundays and on Christian holidays. They also lacked religious imagery, which may have made them appear more welcoming for Jews.

Combined, these factors caused the number of Chinese restaurants in urban East Coast cities to skyrocket during the early 20th century. Jews soon accounted for 60 percent of the white clientele in New York City's and Philadelphia’s Chinese restaurants, Chen writes, and Chinese restaurants would often go out of their way to cater to these clients. The eateries delivered their food to Jewish neighborhoods and to individual customers.

Yet an unwavering affection for Chinese food wasn't shared by all Jews. In an example cited by Chen and Lee, a reporter for Der Tog (The Day), a Yiddish daily newspaper in New York City, noted in 1928 that Jewish diners were in danger of drowning their culinary roots in soy sauce. To take back their taste buds, Jewish-Americans should hoist protest signs reading “Down with chop suey! Long live gefilte fish!” the journalist joked.

But Jewish cookbooks had already begun including Americanized dishes like chop suey and egg foo yung, which Chinese chefs had specially created to appeal to homegrown appetites. And as Lower East Side Jews moved to different neighborhoods, boroughs, and suburbs, Chinese restaurants followed them.

By the mid-20th century, Nathan says, Chinese restaurants had become de facto social clubs in Jewish communities. Familiar faces were always present, children were always welcome, and eating with your hands wasn’t just encouraged—it was required. Everyone left filled with food and gossip, whether it was Christmas or an ordinary Sunday evening.

Thanks to immigration patterns, nostalgia, and convenient hours of operation, this culinary custom has stuck around. “Jewish guests want to go out and eat Chinese food on Christmas,” Schoenfeld, the Manhattan restaurateur, says. “It’s become a tradition, and it’s extraordinary how it’s really grown.”
