Pizza is cooked in a oven. When cooked, it should be crispy, tender and fragrant. Neapolitan pizza has gained the status of "guaranteed traditional specialty" in Italy. This admits only three official variants: Pizza marinara, which is made with tomato, garlic, oregano and extra virgin olive oil (although most Neapolitan pizzerias also add basil to the marinara), Pizza Margherita, made with tomato,mozzarella, basil and extra virgin olive oil, and Pizza Margherita DOC made with tomato, buffalo mozzarella from Campania in fillets, basil and extra virgin olive oil.
