Prosciutto cotto literally means cooked ham in Italian. It is the most commonly used deli product in Italy. A prosciutto cotto differs from an American ham in several ways. First, the skin is left on the top of the product (like prosciutto di Parma) to keep in moisture and flavors. Second, the prosciutto is cooked very slowly creating a unique flaky texture. Third, the spices used are more aromatic and there is no smoking or sweetening making a more delicate flavor.
It is also very low in sodium. The uses of the prosciutto cotto are as many as the uses of ham with sandwiches and pizzas being most common.
