Clean and boil the brains in salted water; add 1 onion sliced; let cook ten minutes. Remove the brains and mash up well with 1 tablespoonful of butter, some bread-crumbs and parsley chopped, salt and pepper to taste; add 2 eggs. Mix together and fry in deep hot lard by the tablespoonful until brown. Serve with tomato-sauce.
