Parmesan is used to describe cheeses made like Parmigiano Reggiano (considered true Parmesan cheese), especially outside of Europe. It has a sharp, piquant flavor that requires ten months to develop. Parmesan is usually grated or shaved and ideal to use over pasta, as well as stirred into soup or risotto. Parmesan is a key ingredient in certain pasta sauces such as Alfredo and pesto. Many people enjoy the taste of Parmesan sprinkled over popcorn, on Italian bread, melted into sauces or grated over a salad.
