Pepperoni is a type of salami that is made from beef and pork.
The meat is ground up and mixed with spices, such as paprika, garlic, and fennel seeds.
The mixture is then stuffed into casings and left to cure for several weeks.
During the curing process, the pepperoni is fermented, which gives it its tangy flavor.
After curing, the pepperoni is sliced and ready to be used as a pizza topping or in other dishes.
While pepperoni is a popular topping, it is high in calories, fat, and sodium, so it should be consumed in moderation.
