In the United States, calzones are characteristically made from pizza dough and stuffed with meats, cheeses, and vegetables. Traditional calzone dough consists of flour, yeast, olive oil, water, and salt. Calzones are similar to stromboli, but traditionally the two are distinct dishes.
As a rule, calzones are usually stuffed with cheeses such as ricotta, mozzarella, Parmesan, Provolone or a type of regional cheese. The dough is folded into a half-moon shape then sealed with an egg wash mixture, or formed into a spherical shape and baked or fried. After cooking, calzones are typically served smothered in marinara sauce or topped with a combination of garlic, olive oil, and parsley.
