Two cupfuls of smoothly mashed boiled or baked potatoes, two
tablespoonfuls of melted butter, two well-beaten whites of eggs, a
cupful of sweet cream or rich milk. Stir the melted butter into the
potato, then add the eggs and cream, season with salt and pepper, turn
into a buttered baking dish, bake in a quick oven and serve in the dish
in which it is baked.
