Parmigiano Reggiano is a hard grating type of Italian grana cheese. It is considered to be the very best of the grana cheeses, usually aged for 2 years and sold very expensive.
There are many imitations of this cheese, but the true Parmigiano Reggiano has a grainy, crumbly texture and a fragrant, delicate aroma. It has been made for many centuries in the Northern part of Italy, the area comprising Reggio Emilio, Parma, Modena and parts of Bologna and Mantua.
Parmigiano Reggiano goes well with pasta, pasta sauces, pizza, risotto, and salads or cut into slivers and eaten alone.
