Neapolitan pizza (Italian: pizza napoletana) also known as Naples-style pizza, is a style of pizza made with tomatoes and mozzarella cheese. It must be made with either San Marzano tomatoes or Pomodorino del Piennolo del Vesuvio, which grow on the volcanic plains to the south of Mount Vesuvius, and Mozzarella di Bufala Campana, a protected designation of origin cheese made with the milk from water buffalo raised in the marshlands of Campania and Lazio in a semi-wild state, or Fior di Latte di Agerola, a cow milk mozzarella made exclusively in the Agerola comune. Neapolitan pizza is a Traditional Speciality Guaranteed (TSG) product in Europe, and the art of its making is included on UNESCO's list of intangible cultural heritage. This style of pizza gave rise to the New York-style pizza that was first made by Italian immigrants to the United States in the early 20th century.
