Pepperoni, an American salami sausage, is typically made from cured pork and beef. Recipes for pepperoni also include a variety of spices, such as cayenne pepper, salt, sugar, crushed anise seed and garlic. Pepperoni is stuffed into casing from a pig's intestines.
Pepperoni can be made with other meats, including duck, turkey, deer and fish. Pepperoni is a dry cured type of salami. A healthy bacterium develops in the curing process, preventing the meat from rotting. The pork casing holds the meat and spices in an airtight vessel that also helps to keep the pepperoni fresh. Pepperoni is a popular topping on American-style pizzas.
