Neapolitan pizza ("pizza Napoletana"). Authentic Neapolitan pizzas are made with local ingredients like San Marzano tomatoes, which grow on the volcanic plains to the south of Mount Vesuvius and Mozzarella di Bufala Campana, made with the milk from water buffalo raised in the marshlands of Campania and Lazio in a semi-wild state (this mozzarella is protected by its own European law).
