Peel and core four fine, sound pippin apples.

Put them into a saucepan with two ounces of boiled and peeled chestnuts, and a piece of cinnamon an inch long. Toss well on the fire for ten minutes, then transfer them to a copper basin, stirring in a teaspoonful of corn-starch, and adding a quarter of a pound of powdered sugar. Place on a slow stove for ten minutes, then put aside. When thoroughly cooled, add three egg yolks and one whole one ; mix well with a wooden spatula, and the preparation will be ready for use. Take a three-pint, square mold, butter it lightly, and with a small hair-brush sprinkle in a little powdered sugar, and pour in the prepared apple. Place the mold in a tin pastry-pan, filling the latter to half the height of the mold with cold water, and place the whole in a moderate oven for thirty minutes. Take the mold from the pan, and lay on top of it a hot, deep dessert-dish, slightly larger than the cake ; turn the mold bottom up, and lift it off, leaving the cake on the dish. While the cake is in the oven, prepare the following sauce : mix in a saucepan two egg yolks, one ounce of powdered sugar, half a pint of water, and half a teaspoonful of ground cinnamon. Place on a brisk fire, and stir constantly for five minutes, not allowing it to boil. When the cream is ready, add half a glassful or a gill of rum, or any other kind of liquor. Mix well for half a minute, pour the sauce over the cake, and serve very hot.
