Cake ingredients: Cake directions: Beat egg yokes until thick and lemon colored. Add confectioners' sugar gradually, beating constantly. Sift flour and salt together and fold into yolk mixture. Beat egg whites until stiff enough to hold a peak and fold in lightly. Line seven-layer cake pans with paper and grease the paper. Divide batter evenly among pans and bake in moderate oven (350 degrees F.) for dozen minutes. Remove from pans at once. Frosting (filling) directions: For the frosting, heat chocolate and water in the top of double boiler. Mix eggs and sugar thoroughly, combine with melted chocolate and cook until thick, stirring constantly. Remove from heat; add butter and beat until well blended. Add vanilla and continue beating until filling is stiff enough to spread. Cover each layer and top and sides of cake with filling. NOTE: It may be necessary to place several toothpicks through the top layers to hold them in place until filling sets. Serve after 24 hours. Serves 14 to 16.
