Birds' Nest Pudding

Core and peel eight apples, put in a dish, fill the places from which the cores have been taken with sugar and a little grated nutmeg; cover and bake. Beat the yolks of four eggs light, add two teacupfuls of flour, with three even teaspoonfuls of baking powder sifted with it, one pint of milk with a teaspoonful of salt; then add the whites of the eggs well beaten, pour over the apples and bake one hour in a moderate oven. Serve with sauce.
