Mix four and a half ounces of breadcrumbs, four ounces of Parmesan cheese, two ounces of butter, half a teaspoonful of cayenne pepper and salt, and two eggs; pound these all thoroughly in a mortar, bind them with a well-beaten egg, shape into balls about the size of a walnut, egg and breadcrumb them and fry a golden brown in plenty of boiling fat. Drain well, and serve at once very hot, garnished with parsley.
