Apple Souffle 1

One pint of steamed apple, one table-spoonful of melted butter, half a cupful of sugar, the whites of six eggs and the yolks of three, a slight grating of nutmeg. Stir into the hot apple the butter, sugar and nutmeg, and the yolks of the eggs, well beaten. When this is cold, beat the whites of the eggs to a stiff froth, and stir into the mixture. Butter a three-pint dish, and turn the soufflé into it. Bake thirty minutes in a moderate oven. Serve immediately with any kind of sauce.
