Cook 12 apples as for sauce, beat well with an egg beater, sweeten, and add the juice of 1 lemon, whip the whites of 4 eggs to a stiff froth, and mix with the apples. Make a custard of 1 1/2 pts. of rich milk, one large cupful of sugar, and the yolks of 4 eggs. When perfectly cold pour over the apple mixture, which must be stiff and cold to prevent rising in the custard. Finally whip 1/2 pt. of rich cream and spread on top of the custard.
