Calzone[a][1] is an Italian oven-baked turnover[2][3] It originated in Naples in the 18th century.

[4] A typical calzone is made from salted bread dough, baked in an oven and stuffed with prosciutto or salami, mozzarella or ricotta, and Parmesan or pecorino, as well as an egg.

[12] Sandwich-sized calzones are often sold at Italian lunch counters or by street vendors, because they are easy to eat while standing or walking.

[13] Fried versions of the calzone are typically filled with tomato and mozzarella; these are made in Apulia and are called "panzerotti".

[15] Pork (or, more rarely, goat meat), eggs, and cheese are main ingredients for the filling.
