Parmesan cheese
Within the European Union, the term Parmesan may only be used, by law, to refer to Parmigiano-Reggiano itself, which must be made in a restricted geographic area, using stringently defined methods. In many areas outside Europe, the name "Parmesan" has become genericized: Any one of a number of hard Italian-style grating cheeses are called 'Patmesan'. After the European ruling that "parmesan" could not be used as a generic name, Kraft renamed its grated cheese "Pamesello" in Europe.
