Older recipes for this risotto often stipulated that cervellata, a Milanese sausage of pork sirloin with pork and veal fat, pig???s brain (hence the name of the sausage), Parmigiano-Reggiano cheese, and spices such as saffron and nutmeg, should be used.[photo: risotto alla milanese with ossobuco, Clifford A.
