The term pizza was first recorded in the year 997 AD, in a Latin manuscript from the southern Italian town of Gaeta, in Lazio, on the border with Campania.[3] Raffaele Esposito is often credited for creating modern pizza in Naples.[4][5][6][7] In 2009, Neapolitan pizza[8] was registered with the European Union as a traditional speciality guaranteed (TSG) dish. In 2017, the art of making Neapolitan pizza was added to UNESCO’s list of intangible cultural heritage.[9]
Pizza and its variants are among the most popular foods in the world. Pizza is sold at a variety of restaurants, including pizzerias (pizza specialty restaurants), Mediterranean restaurants, via delivery, and as street food.[10] In Italy, pizza served in a restaurant is presented unsliced, and is eaten with the use of a knife and fork.[11][12] In casual settings, however, it is typically cut into slices to be eaten while held in the hand. Pizza is also sold in grocery stores in a variety of forms, including frozen or as kits for self-assembly. They are then cooked using a home oven.
