Boil the macaroni. Then drain well. Put a tablespoonful of butter into a saucepan, add the Macaroni and sprinkle over the grated cheese and the minced smoked tongue and truffle. Toss all together nicely and then spread out evenly. Then set aside to cool. When cool cut the preparation into six equal parts and roll each in grated Parmesan cheese, then in a well-beaten egg, and afterwards in freshly-grated bread crumbs. Have ready a pan of boiling lard, fry the Croquettes in the lard for five minutes, drain well, place on a dish on a folded napkin and serve hot.
