Cooking
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, 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). Prior to use, a peel may be sprinkled with cornmeal to allow pizza to easily slide onto and off of it. When made at home, it can be baked on a pizza stone in a regular oven to reproduce 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.
Pizza is a flatbread generally topped with tomato sauce and cheese and baked in an oven. It is commonly topped with a selection of meats, vegetables and condiments. The term was first recorded in the 10th century, in a Latin manuscript from Gaeta in Central Italy. The modern pizza was invented in Naples, Italy, and the dish and its variants have since become popular in many areas of the world.
In 2009, upon Italy's request, Neapolitan pizza was safeguarded in the European Union as a Traditional Speciality Guaranteed dish. The Associazione Verace Pizza Napoletana (the True Neapolitan Pizza Association) is a non-profit organization founded in 1984 with headquarters in Naples. It promotes and protects the "true Neapolitan pizza".
Pizza is sold fresh, frozen or in portions. Various types of ovens are used to cook them and many varieties exist. Several similar dishes are prepared from ingredients commonly used in pizza preparation, such as calzone and stromboli.
