Tortellini is a ring-shaped pasta; they are typically stuffed with a mix of meat (pork loin, prosciutto crudo, mortadella) and parmesan cheese, although other stuffings are popular in the Po Valley. Originally from the Italian region of Emilia (in particular Bologna and Modena), they are usually served in broth, with cream, or with a ragù or similar sauce. Traditionally, the most serious restaurant in Bologna as well "La Confraternita del Tortellino" agree that the only real Tortellino is served only in home made broth.
