Brine Time: The Science Behind Salting 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 they have to find enough room in their 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; that is, 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.

These Suitcases Convert Into a Mini Kitchen, Office, or Bed

Finally, a product has been released to appease travelers who have long demanded a suitcase they can cook scrambled eggs on. A new line by Italian designer Marc Sadler, spotted by Lonely Planet, features three aluminum suitcases that can be converted into either a mini kitchen, a work station, or even a bed.

The cook station suitcase will soon be released as part of the special edition Bank collection, which will be sold by suitcase brand Fabbrica Pelletterie Milano. It comes with built-in power, a cooktop, mini fridge, several drawers with cutlery, and a foldable chopping table.

Those who travel often for work may want to opt instead for the workstation suitcase, which features a pull-out chair, work surface, electrical outlets, and wooden drawers. Ideal for camping, the bed station comes with a fold-out wooden frame and mattress topper. It also happens to be the most expensive of the three, at a cost of €6900 ($8135).

It's unclear whether these suitcases would make it through airport security, but TSA does permit camp stoves as long as they don't have fuel inside them. Don't try to make breakfast while waiting at your gate, though—there are probably rules against that.

Chefs Launch World's Highest Pop-Up Restaurant at Mt. Everest Base Camp

A touch of altitude sickness shouldn't stand in the way of a good meal. At least that seems to be the idea behind a plan to serve a seven-course dinner to trekkers at Everest Base Camp, the gateway for those planning to climb Mt. Everest in Nepal.

The four chefs leading this trip hope it will land them a new Guinness World Record for the highest pop-up restaurant on the planet, according to Architectural Digest. At the end of May, the chefs will take 10 people on an eight-day trek from the town of Lukla (at an altitude of about 10,000 feet) to Everest Base Camp (at 11,600 feet), all while foraging along the way for ingredients that can be incorporated into the meal. (For a true luxury experience, guests also have the option of traveling by helicopter.) The full package of flights, accommodations, and meals costs about $5600 per person.

After reaching their destination, trekkers will get to sit back and enjoy a feast, which will be served inside a tent to protect diners against the harsh Himalayan winds. Indian chef Sanjay Thakur and others on his team say they want to highlight the importance of sustainability, and the money they raise will be donated to local charities. Thakur said most of the food will be cooked sous vide, which allows vacuum-packed food to be cooked in water over a long period of time.

"The biggest challenge, of course, will be the altitude, which will affect everything," Thakur tells Fine Dining Lovers. "Flavor [perception] will be decreased, so we will be designing a menu of extraordinary dishes accordingly, where spices will have the upper hand."

This isn't the first time an elaborate meal will be served at Everest Base Camp, though. According to Fine Dining Lovers, another chef launched a pop-up at the same spot in 2016, but it presumably wasn't registered with the Guinness Book of World Records. Other extreme restaurants include one carved into a limestone cliff in China, one dangling 16 feet above the ground in a rainforest in Thailand, and one submerged 16 feet below sea level in the Maldives.
