'Neapolitan pizza' is a highly specific (and tightly regulated) distinction

New Haven 'apizza' nods to Naples and New England

The thin pizza, called "apizza," is crispier than the typical slice from New York or a national chain, and much more like the thin-crust pizzas associated with pizza's birthplace. It's also got some inspired toppings, with one popular pie that speaks to New England's love of seafood: the white clam pie.

Pizza is believed to have been invented in Naples

Flatbreads were eaten by ancient Egyptians, Romans, and Greeks, but historians trace pizza—flatbread with toppings, including present-day staples like tomatoes, cheese, garlic, oregano, and oil—back to 18th-century Naples, where the food was loved by its working poor, who appreciated a cheap, tasty meal. Naples formally became a part of Italy in 1861.

Legend has it that the Margherita pizza was named after an encounter with Queen Margherita

The Queen of Italy, Margherita of Savoy, visited Naples in 1889. As the story goes, chef Raffaele Esposito of Pizzeria Brandi made her a pizza with basil, mozzarella, and tomato, to represent the colors of the Italian flag, and eventually named the pie in her honor. Historians, however, note that the facts don't line up: The proof of her visit to the pizzeria is suspected to be a forgery created when the business was in dire straits in the 1930s.

One food history professor says pizza is more American than Italian

Alberto Grandi, a professor at the University of Parma, argues that Italians who left the country developed the food now considered "traditional Italian cuisine," thanks to abundant ingredients and opportunities that were not available in the impoverished country they left behind.

One baker is likely responsible for several of New York's earliest pizzerias

Filippo Milone established at least six pizzerias in New York, including one that would later be called Lombardi's, widely considered to be the city's (and the country's) first pizza establishment. Milone died in 1924, leaving no children to tell his story. Researcher Peter Regas unearthed a 1903 advertisement, pictured below, from an Italian-language New York newspaper.

Detroit-style pizza's recipe nods to the Motor City

Napa's growing conditions are unique

The French term "terroir" refers to the "sense of place" that growing conditions impart on a wine. Because the Napa Valley is surrounded by mountains on three sides, the combination of cold air from the Pacific coast and warm air from inland leaves Napa's wine with a distinct terroir.

NASA funded research into creating pizza with a 3D printer

The agency awarded a contract for the development of devices that can create edible structures from long-lasting dry powders when mixed with liquids or pastes. By delaying this integration until the time of consumption, food could last longer than the current six-month expiration of freeze-dried meals for Mars expeditions.

Pizzagate alleged a neighborhood pizza joint was hosting a sex trafficking scheme

'Pastafarians' have used their pasta-strainer-wearing faith to test the legal limits of what counts as religion

Founded in 2005 to mock the teaching of creationism in public schools, the Church of the Flying Spaghetti Monster has led to real First Amendment cases—over driver's license photos, courthouse statues, and prison rights. Courts have generally ruled it as satire rather than religion.

Domino's Pizza's 30-minute guarantee was discontinued after a string of delivery-driver accidents

The chain's promotional gimmick offered customers free or reduced pizzas if their pizzas weren't delivered in 30 minutes or less. That policy led to the chain's popularity, but it also led to reckless driving: In the late '80s, the National Safe Workplace claimed its drivers had the same death rate as miners. After Domino's was found liable in 1993 for nearly $79M in damages, it discontinued the policy.

Pumpernickel is a dark rye bread made without wheat flour in Germany and exported to over 100 countries. It's one of the oldest breads in the world, having been made for at least 500 years.

Why this legally can't be called 'ice cream'

Dairy Queen doesn't technically sell 'ice cream' and it all comes down to milkfat. According to FDA rules, anything labeled 'ice cream' must have at least 10% milkfat. Dairy Queen’s soft serve only has 5%, which means it's legally in a different category.

Funazushi takes 3 years to prepare

Funazushi is a type of honnare (sometimes spelled hon-nare or called narezushi) sushi. Unlike nigirizushi, the quicker form that's commonly found in restaurants, honnare is preserved over a long stretch of time. Mariko Kitamura, who runs a funazushi shop in Takashima City, Japan, describes the dish as a "fish version of prosciutto" with a saltiness that's similar to caviar.

USP-verified label on supplements means a nonprofit confirmed what's in the bottle

The black-and-yellow USP-verified program seal on a dietary supplement bottle means that the nonprofit US Pharmacopeia tested a sample of the product and verified that it was made in a facility with good manufacturing practices and that it will dissolve in the body. Their certification also means they tested to confirm that the product contains the ingredients listed on the bottle at the specified levels, and that it doesn't contain harmful levels of certain dangerous contaminants.

Chemistry-informed advice for cooking pasta, including how to prevent clumping noodles

On a molecular level, pasta dough consists of protein structures that hold starch molecules, and the starches absorb water during cooking, forming a gel that softens the pasta. Pasta should not be rinsed after cooking. Instead, some of the pasta water should be added to the pasta sauce, as the gelatinous starch will help the sauce stick to the pasta.

Cinco de Mayo is a regional holiday concentrated in Puebla and celebrated with local cuisine

Vegan cheesemaking relies heavily on nuts and seeds

We might associate vegan cheese with current health trends, but there’s actually been a small-but-growing market for plant-based cheeses since the 19th century. But for vegan cheeses to appeal to a wider demographic, they have to compete with the familiar flavors and textures of dairy cheeses.
