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 might(depending on region) be served with marinara sauce or topped with a combination of garlic, olive oil, and parsley.
Scacciata is similar to a calzone but is filled with either broccoli, spinach, potatoes or onions, and sometimes sausage. A sausage roll is a dish similar to a calzone developed in Fort Wayne, Indiana. It is folded at the top, rather than along the edge. They did not develop from calzones, though, instead coming from rolled-up pizzas, similar to sausage bread.[6]
