Apple sauce omelet (baked)

Beat the yolks of seven eggs light; stir into them five tablespoonfuls of powdered sugar and a cupful and a half of sweetened apple sauce. Beat long and hard, stir in the stiffened whites, beat for a minute longer and turn into a greased pudding-dish. Bake, covered, for about ten minutes, then uncover and brown. Serve at once with whipped cream. It is also good served with a hot sauce made by the following recipe:

Into a pint of boiling water stir a half-cupful of sugar, and when this dissolves add a teaspoonful of butter, the juice and the grated rind of a lemon and the stiffened white of an egg. Beat for a minute over the fire, but do not let the sauce boil.
