6 cold boiled potatoes 2 cups of milk
2 tablespoons of butter or butter substitute
3 tablespoons of flour
4 heaping tablespoons grated cheese
Salt and pepper to taste
Put the butter or butter substitute in a frying-pan to melt; when melted, add the flour, mix until smooth; then add the milk, and stir continually until it boils. Take from the fire, add the cheese, salt, and pepper. Put a layer of this sauce in the bottom of a baking-dish, then a layer of the cold potatoes, sliced, and so on, having the last layer sauce; sprinkle bread crumbs over the top, and put it in a quick oven ten minutes, to brown. Serve in the dish in which it was baked.
To two cups of well-seasoned mashed potatoes add the beaten yolks of two eggs, a tablespoon of chopped parsley, one and a half tablespoons of butter or butter substitute (if none has been used in seasoning), a dash of cayenne and nutmeg; stir over the fire until the potato leaves the sides of the pan. When cold, form it into small croquettes, roll them in egg and bread crumbs and fry them in hot deep fat to an amber color.
