Pizza

Pizza is a world-popular dish of Italian origin, made with an oven-baked, flat, generally round bread that is often covered with tomatoes or a tomato-based sauce and mozzarella cheese. Other toppings are added according to region, culture, or personal preference. Originating in a part of Italian cuisine, the dish has become popular in many different parts of the world. A shop or restaurant where pizzas are made and sold is called a "pizzeria". The phrases "pizza parlor", "pizza place" and "pizza shop" are used in the United States. The term pizza pie is dialectal, and pie is used for simplicity in some contexts, such as among pizzeria staff.

The bottom base of the pizza (called the "crust" in the United States and Canada) may vary widely according to style thin as in hand-tossed pizza or Roman pizza, thick as in pan pizza or Chicago-style pizza. It is traditionally plain, but may also be seasoned with butter, garlic, or herbs, or stuffed with cheese. In restaurants, pizza can be baked in an oven with stone bricks above the heat source, an electric deck oven, a conveyor belt oven or, in the case of more expensive restaurants, a wood- or coal-fired brick oven. On deck ovens, the pizza can be slid into the oven on a long paddle called a peel and baked directly on the hot bricks or baked on a screen (a round metal grate, typically aluminum). When making pizza at home, it can be baked on a pizza stone in a regular oven to imitate the effect of a brick oven. Another option is grilled pizza, in which the crust is baked directly on a barbecue grill. Greek pizza, like Chicago-style pizza, is baked in a pan rather than directly on the bricks of the pizza oven.

American pizza often has vegetable oil or shortening (often, but not always, olive oil) mixed into the dough; this is not as common in Italian recipes. This can range from a small amount in relatively lean doughs, such as New York style, to a very large amount in some recipes for Chicago-style deep-dish dough. In addition, American pizza (at least thin-crust) is often made with a very high-gluten flour of the type also used to make bagels; this type of flour allows the dough to be stretched rather thinly without tearing, similar to strudel or phyllo dough.

New York-style pizza is a style originally developed in New York City by immigrants from Naples, where pizza was created. It is often sold in generously sized, thin and flexible slices. It is traditionally hand-tossed, moderate on sauce, and moderately covered with cheese essentially amounting to a much larger version of the Neapolitan style. The slices are sometimes eaten folded in half, or even stacked, as its size and flexibility may otherwise make it unwieldy to eat by hand. This style of pizza tends to dominate the Northeastern states, and is very similar to the basic style common through the United States and known simply as pizza. "Neapolitan", or "regular", made with a relatively thin, circular crust and served in wedge-shaped slices, and "Sicilian", or "square", made with a thicker, rectangular crust and served in large, rectangular slices. It is cooked in a square pan like Sicilian, but it is much thinner. It has a thin, crispy crust, usually has tomato chunks in addition, or in exception, to the sauce. Generally, it will contain less cheese than regular slices, and sometimes has extra spices or oils baked into the crust.
