     2/3  cup           sugar
   7                    eggs
     3/4  cup           all-purpose flour
   3      tablespoons   cornstarch
   2      teaspoons     grated lemon rind
                        ***FILLING***
   3      cups          whipping cream
   6      ounces        semi-sweet chocolate
                        chips
     1/4  cup           amaretto
   1      9 inch        genoise -- split

Preparation:

In a bowl, mix eggs and sugar. Heat over hot water to 115F, beating until doubled in volume. Sift flour and cornstarch together 3 times. Carefully fold the flour, cornstarch and lemon rind into the egg mixture. Pour into greased and floured 9-inch cake pans. Bake at 425F until set and springy. Remove from pans and cool on cake racks. ***AMARETTO/CHOCOLATE FILLING*** Heat cream to 180F. Stir in chocolate chips and remove from the heat. Stir to melt, then chill overnight. Put half of the genoise on a cake pan and sprinkle with half of the Amaretto. Whip the cream mixture until stiff. Spread 1/4 of the mixture on the cake. Add top layer of cake and sprinkle with the remaining Amaretto. Ice top and sides of cake with chocolate filling, reserving some it to pipe through a pastry bag for finishing touches.
