A calzone is an Italian filled oven bread, originating in Naples, and shaped as a folded pizza. It resembles a half-moon and is made of salted bread dough. A typical calzone is baked in an oven and stuffed with salami or ham, mozzarella, ricotta and Parmesan or pecorino cheese, amalgamated with an egg. Its regional variations include other ingredients that are normally associated with pizza toppings. Calzones of smaller dimension can also be fried in olive oil.
