Pepperoni

Pepperoni is a variety of spicy salami made from cured pork and beef seasoned with paprika and chili peppers.

Prior to cooking, pepperoni is characteristically soft, slightly smoky, and bright red. Sliced pepperoni is one of the most popular pizza toppings in American pizzerias.

Traditionally made pepperonis curl into "cups" in the pizza oven's intense heat; commercialization of the production of pepperoni created slices that would lie flat on the pie. The curled "cup and char" style of pepperoni remained popular in pockets of the Midwest.

Etymology
The term pepperoni is a borrowing of peperoni, the plural of peperone, the Italian word for 'bell pepper'. The first use of pepperoni to refer to a sausage dates to 1916 at the latest. In Italian, the word peperoncino refers to hot and spicy chili peppers.

History
In 1919, Italian immigrants in New York City created pepperoni. It is a cured dry sausage, with similarities to the spicy salamis of southern Italy on which it is based, such as salsiccia or soppressata. The main differences are that pepperoni is less spicy, has a finer grain (akin to spiceless salami from Milan), is usually softer in texture, and is usually produced with the use of an artificial casing.

Production
Pepperoni is made from pork or from a mixture of pork and beef. Turkey meat is also commonly used as a substitute, but the use of poultry in pepperoni must be appropriately labeled in the United States. It is typically seasoned with paprika or other chili pepper.

Prior to cooking, pepperoni is characteristically soft, slightly smoky, and bright red. Curing with nitrates or nitrites (usually used in modern curing agents to protect against botulism and other forms of microbiological decay) also contributes to pepperoni's reddish color, by reacting with heme in the myoglobin of the proteinaceous components of the meat.

Serving
Sliced pepperoni is one of the most popular pizza toppings in American pizzerias. According to Convenience Store Decisions, in 2009 Americans consumed 251.7 e6lb of pepperoni annually, on 36% of all pizzas produced nationally.

Pepperoni is also used as the filling of the pepperoni roll, a popular regional snack in West Virginia and neighboring areas.

In the Canadian province of Nova Scotia, deep fried pepperoni served on its own (usually with a honey mustard dipping sauce) is common pub food.

Cup and char
Pepperoni has a tendency to curl up from the edges in the heat of a pizza oven; historically all pepperonis showed at least some of this tendency to curl in the oven because of their natural casings.

As commercial suppliers became the main suppliers to pizza shops, they developed a fibrous synthetic casing which is intended to be stripped from the pepperoni before it is sliced. This resulted in a pepperoni that does not curl. An additional benefit of non-curling pepperoni is that it eliminates the small deposits of hot grease that formed in the cupped pepperoni, therefore also eliminating any possible liability for customers who burn themselves on it.

The original style became known as "cup and char" pepperoni and remains popular in parts of the midwest and Great Lakes areas, particularly around Cleveland, Ohio, and Buffalo, New York, and regained popularity in other areas in the 2010s. It is more expensive to produce.
