Potato Cakes

Beat two cups of left-over mashed potatoes with a very little hot milk to lighten them. Season with a few drops onion juice, salt, pepper, one-half teaspoon parsley finely chopped, and one-fourth cup grated cheese and a few grains cayenne. Shape in small round flat cakes, dip in flour and saute in hot butter (about two tablespoons), brown on one side, turn and brown on the other. This mixture may be packed in a brick-shape mold, then turned on a board and sliced, dipped in flour and sauted in butter as the round cakes.
