One food history professor says pizza is more American than Italian

Pizza became more popular in Italy after it took off in the US

Pizza was invented in Naples, though it wasn't particularly popular outside the region. As it grew more popular elsewhere—and as more American and European tourists visiting Italy began asking for it—restaurants across Italy adopted the cuisine. It's something anthropologist Agehananda Bharati calls "the pizza effect."

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.

Italian immigrants brought pizza to Argentina in the late 19th century

Two million Italians emigrated to Argentina between 1880 and 1920, many of them the poor who regularly ate pizza. In Argentina, they were pleased to find that mozzarella was plentiful, allowing them to make cheesier pies. By 1882, Italians owned 126 of the 198 bakeries in Buenos Aires, as well as the majority of shops selling butter, cheese, and pasta.

After World War II, pizza took off in the US

Pizzerias opened in cities throughout the 1920s and '30s, especially those with large Italian immigrant populations, but the cuisine didn't take off nationally until after World War II. Some credit that with American soldiers' exposure to the food while stationed in Italy; others point to the invention of the mass-produced gas-fired ovens, which made opening a pizzeria considerably easier. Below is a 1944 clip from the New York Times, the first time the paper mentioned pizza.

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.

Chicago deep-dish pizza arrived in 1943

Pizzeria Uno was the first establishment to sell the concoction, which turned more traditional pizza upside down, with cheese as the base and sauce as the topping. Soon, Uno employees went out on their own, sparking a citywide deep-dish phenomenon.

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.

A look at what was on the menu for ancient Romans

"Delicious Italy" is a website exploring the food culture of various Italian cities and regions, and in this article, the editors explore what is known about the diet of ancient Romans. Olives (and their oil) were a key daily essential, alongside grains like barley, millet, and spelt flour. Where meat was found it was most often ox, pork, deer, lamb, and even pigeons. Middle Eastern fruits like cherries and peaches could last long enough to travel to Roman cities around the Mediterranean, and candy-friendly dates were sourced from Africa. Explore this and much more at Delicious Italy.

How the Bank of Italy became Bank of America

Amid the devastation of the 1906 earthquake in San Francisco, Italian immigrant and local banker Amodei Giannini managed to keep hold of a substantial amount of currency.

How the Great Depression still shapes the way Americans eat

From fortified foods to nutrition labels, the legacy of an early financial crisis lives on in kitchens across the United States. Ethnic foods with their (supposedly) hunger-triggering spices were vilified and considered “stimulants” along the lines of caffeine and so, in their stead came prune puddings, canned-meat stews, and dairy-heavy vegetable casseroles featuring America’s first fortified foods. Read more here.

The bizarre 1920 proposal to form a pizza-shaped central European state

How Byzantine scholars supercharged Renaissance Italy

A brief survey of how Byzantine scholars changed the course of the Renaissance by introducing Classical Greek literature to Italy.

The difference between ice cream, gelato, sorbet, and Italian ice

Ice cream is made of eggs and is high in fat, served cold. Gelato, on the other hand, has more milk and less cream, and is typically served warmer than ice cream. Sorbet is dairy-free and often includes alcohol, while Italian ice is grainy, lighter, and low in calories (and often doesn't contain dairy).

Tex-Mex is its own distinct cuisine with roots in the Texas borderlands
