Make a short pie-crust; roll it thin and cut it into squares large enough to cover an apple. Select apples of the same size; pare them; remove the core with a corer, and fill the space with sugar, butter, a little ground cinnamon, and nutmeg. Place an apple in the center of each square of pie-crust; wet the edges with white of egg and fold together, the points meeting on the top; give the edges a pinch and turn, making them fluted. Bake in a moderate oven about forty minutes, or until the apples are tender, but not until they have lost their form. If preferred, the crust may be folded under the apple, leaving it round. It must be well joined, so the juices will not escape. Brush the top with egg, and ten minutes before removing from the oven dust them with a little sugar to give them a glaze. Serve with hard sauce.
