Parmesan is a hard, aged cheese that originates from Italy, specifically the regions of Parma, Reggio Emilia, Modena, Bologna, and Mantua. It is made from cow's milk and is known for its rich, nutty flavor and granular texture. Authentic Parmesan is often labeled as Parmigiano-Reggiano, which indicates it meets strict production standards. This cheese is typically aged for a minimum of 12 months, with some varieties aged for up to 36 months or more. Parmesan is commonly used in cooking, grated over pasta dishes, salads, and soups, or enjoyed on its own as a snack. Its versatility and strong flavor make it a popular choice in many cuisines.
