This 3D-Printed Sushi is Customized For You Based on the Biological Sample You Send In

Many high-end restaurants require guests to make a reservation before they dine. At Sushi Singularity in Tokyo, diners will be asked to send fecal samples to achieve the ideal experience. As designboom reports, the new sushi restaurant from Open Meals creates custom sushi recipes to fit each customer's nutritional needs.

Open Meals is known for its experimental food projects, like the "sushi teleportation" concept, which has robotic arms serving up sushi in the form of 3D-printed cubes. This upcoming venture takes the idea of a futuristic sushi restaurant to new extremes.

Guests who plan on dining at Sushi Singularity will receive a health test kit in the mail, with vials for collecting biological materials like urine, saliva, and feces. After the kit is sent back to the sushi restaurant, the customer's genome and nutritional status will be analyzed and made into a "Health ID." Using that information, Sushi Singularity builds personalized sushi recipes, optimizing ingredients with the nutrients the guest needs most. The restaurant uses a machine to inject raw vitamins and minerals directly into the food.

To make things even more dystopian, all the sushi at Sushi Singularity will be produced by a 3D-printer with giant robotic arms. The menu items make the most of the technology; a cell-cultured tuna in a lattice structure, powdered uni hardened with a CO2 laser, and a highly detailed model of a Japanese castle made from flash-frozen squid are a few of the sushi concepts Open Meals has shared.

The company plans to launch Sushi Singularity in Tokyo some time in 2020. Theirs won't be the first sushi robots to roll out in Japan: The food delivery service Ride On Express debuted sushi delivery robots in the country in 2017.

The Most Popular Christmas Cookie in Each State

While opinions about peppermint bark, reindeer corn, and other Christmas candies are important enough to warrant a map of their own, we all know that the real crown jewel of any kitchen counter during the holidays is an enormous platter of homemade cookies.

In a festive endeavor to guess which type of cookie is most likely to be on your counter this Christmas, General Mills collected search data from BettyCrocker.com, Pillsbury.com, and Tablespoon.com, and created a map that shows which recipes are clicked most often in each state.

Those universally adored Hershey Kiss-topped peanut butter cookies, known on Betty Crocker’s website as Classic Peanut Butter Blossoms, took the top spot in seven states, including Florida, Pennsylvania, California, Kentucky, Nevada, South Carolina, and Wyoming. And people don’t just love peanut butter in blossom form—Easy Peanut Butter Cookie Cups, Peanut Butter-Chocolate Cookies, and 2-Ingredient PB-Chocolate Truffles also made appearances on the list.

Peanut butter treats are definitely a popular choice among holiday bakers in general, and cookie decorators are likely responsible for the prevalence of plain old sugar cookies across the nation. Sugar Cookie Cutouts, Easy Spritz Cookies, and Easy Italian Christmas Cookies all offer a deliciously blank slate for your artistic aspirations.

Apart from peanut butter- and plain sugar-based desserts, the rest of the results were pretty scattered. Iowa most often opts for the figure eight-shaped Swedish Kringla, while Michigan loves a good jam-filled Polish Kolaczki. Surprisingly, Hawaii was the only state to choose gingerbread cookies as their seasonal favorite.

If you’re thinking classic chocolate chip cookies are suspiciously absent from this map altogether, you have great dessert-related detective skills: General Mills decided to omit them from the study, since they’re Betty Crocker’s most-searched cookie recipe all year long, and they would’ve dominated in a staggering 22 states.

Whether you’re looking for a new show-stopping cookie recipe or just wondering how your long-standing family traditions compare to others’, you can read more on the study—and see all the recipes in full—here.

Why Do Fruitcakes Last So Long?

Fruitcake is a shelf-stable food unlike any other. One Ohio family has kept the same fruitcake uneaten (except for periodic taste tests) since it was baked in 1878. In Antarctica, a century-old fruitcake discovered in artifacts left by explorer Robert Falcon Scott’s 1910 expedition remains “almost edible,” according to the researchers who found it. So what is it that makes fruitcake so freakishly hardy?

It comes down to the ingredients. Fruitcake is notoriously dense. Unlike almost any other cake, it’s packed chock-full of already-preserved foods, like dried and candied nuts and fruit. All those dry ingredients don’t give microorganisms enough moisture to reproduce, as Ben Chapman, a food safety specialist at North Carolina State University, explained in 2014. That keeps bacteria from developing on the cake.

Oh, and the booze helps. A good fruitcake involves plenty of alcohol to help it stay shelf-stable for years on end. Immediately after a fruitcake cools, most bakers will wrap it in a cheesecloth soaked in liquor and store it in an airtight container. This keeps mold and yeast from developing on the surface. It also keeps the cake deliciously moist.

In fact, fruitcakes aren’t just capable of surviving unspoiled for months on end; some people contend they’re better that way. Fruitcake fans swear by the aging process, letting their cakes sit for months or even years at a stretch. Like what happens to a wine with age, this allows the tannins in the fruit to mellow, according to the Wisconsin bakery Swiss Colony, which has been selling fruitcakes since the 1960s. As it ages, it becomes even more flavorful, bringing out complex notes that a young fruitcake (or wine) lacks.

If you want your fruitcake to age gracefully, you’ll have to give it a little more hooch every once in a while. If you’re keeping it on the counter in advance of a holiday feast a few weeks away, the King Arthur Flour Company recommends unwrapping it and brushing it with whatever alcohol you’ve chosen (brandy and rum are popular choices) every few days. This is called “feeding” the cake, and should happen every week or so.

The aging process is built into our traditions around fruitcakes. In Great Britain, one wedding tradition calls for the bride and groom to save the top tier of a three-tier fruitcake to eat until the christening of the couple’s first child—presumably at least a year later, if not more.

Though true fruitcake aficionados argue over exactly how long you should be marinating your fruitcake in the fridge, The Spruce says that “it's generally recommended that soaked fruitcake should be consumed within two years.” Which isn't to say that the cake couldn’t last longer, as our century-old Antarctic fruitcake proves. Honestly, it would probably taste OK if you let it sit in brandy for a few days.
