Parmigiano Reggiano

Parmesan, also known as Parmigiano Reggiano, is an Italian hard cheese produced from cow's milk and aged at least 12 months. It is produced in the provinces of Parma and Reggio Emilia, as well as in parts of Bologna, Modena, and Mantua, and is protected by Italian and European law as a designation of origin. The cheese is made from unpasteurized cow's milk and is produced by a consortium of cheese-makers who follow a traditional process of curdling, shaping, and aging the cheese, resulting in a product that is considered to be "practically perfect food".learn more on wikipedia
