Parmesan cheese, known for its exceptional flavor and hard texture, originates from Italy, specifically the regions of Emilia-Romagna and Lombardy. The Italian name for Parmesan is "Parmigiano-Reggiano," which is protected by a designation of origin, meaning it can only be produced in certain areas of Italy under strict regulations. Traditionally made from cow's milk, Parmesan is aged for a minimum of 12 months, often longer, which enhances its flavor profile. This cheese is commonly used in Italian dishes, grated over pasta, or enjoyed on its own. Its popularity has spread globally, making it a staple in many cuisines.
