An authentic Neapolitan pizza has a crust made from a dough that is made with highly-refined Italian type 00 wheat flour, Neapolitan or fresh brewer’s yeast (not dry yeast), water, and salt. The dough must be kneaded and formed by hand, without the help of a rolling pin. The dough is topped with raw, hand crushed San Marzano tomatoes from Italy, fior di latte (mozzarella cheese made from cow’s milk), or mozzarella di Bufala, fresh basil, and extra-virgin olive oil. The ingredients must be all-natural and fresh. The pizza is baked for 60–90 seconds (baking time cannot exceed 90 seconds) in a minimum 850°F (450 degree celsius) oven with a wood fire.
