Margherita Pizza
Almost every American food—from egg foo yung to empanadas—is covered in the phone book under the generic heading “Restaurants.” Only pizza stands alone. Pizza, a Johnny-come-lately compared with such long-standing national favorites as the hamburger and hot dog, has secured a special place on the American table. Everybody likes pizza. Even those who claim to be immune to its charms must deign to have the occasional slice; a staggering 93 percent of Americans eat pizza at least once a month. According to one study, each man, woman, and child consumes an average of 23 pounds of pie every year. - except from http://americanheritage.com/articles/magazine/ah/2006/2/2006_2_30.shtml
In 16th-century Naples, a galette flatbread was referred to as a pizza. Known as the dish for poor people, it was sold in the street and was not considered a kitchen recipe for a long time. This was later replaced by oil, tomatoes (after Europeans came into contact with the Americas) or fish. In 1843, Alexandre Dumas described the diversity of pizza toppings. An often recounted story holds that on June 11, 1889, to honour the Queen consort of Italy, Margherita of Savoy, the Neapolitan pizzamaker Raffaele Esposito created the "Pizza Margherita", a pizza garnished with tomatoes, mozzarella, and basil, to represent the national colours of Italy as on the Flag of Italy.
Pizza evolved into a type of bread and tomato dish, often served with cheese. However, until the late 19th or early 20th century, the dish was sweet, not savory, and earlier versions which were savory more resembled the flat breads now known as schiacciata. Pellegrino Artusi's classic early-twentieth-century cookbook, La Scienza in cucina e l'Arte di mangiar bene gives three recipes for pizza, all of which are sweet. After the feedback of some readers, Artusi added a typed sheet in the 1911 edition (discovered by food historian Alberto Capatti), bound with the volume, with the recipe of "pizza alla napoletana": mozzarella, tomatoes, anchovies and mushrooms.
Pizza crossed the Atlantic with the four million Italians who by the 1920s had sought a better life on American shores. Most Italians weren’t familiar with the many regional variations their fragmented homeland had produced, but a longing for pan-Italian unity inspired a widespread embrace of a simplified pizza as their “national” dish. Fraternal “pizza and sausage” clubs, formed to foster Italian pride, sprouted in cities across the Northeast. Women got in on it too, participating in communal pizza exchanges in which entrants competed with unique pies, some molded into unusual shapes, some with the family name baked into the dough.
Although non-Italians could partake of pizza as early as 1905, when the venerable Lombardi’s—the nation’s first licensed pizzeria—opened its doors in Lower Manhattan, most middle-class Americans stuck to boiled fish and toast. The pungent combination of garlic and oregano signaled pizza as “foreign food,” sure to upset native digestions. If pizza hoped to gain an American following beyond New York City and New Haven, it would have to become less like pizza. By the 1940s a few entrepreneurs had initiated the transformation, starting a craze that forever changed the American culinary landscape.
