½ cup butter, softened
Grated rind of 1 orange
Grated rind of 1 lemon
1 cup sugar
4 egg yolks
1 ½ cups plain flour
1 ½ teaspoons cream of tartar
1 ½ teaspoons baking soda
½ cup cornstarch
¾ cup milk
4 egg whites
Chocolate icing
Preserved fruits or finely chopped pistachio nuts

Beat softened butter in electric mixer until light and creamy. Combine grated orange and lemon rind with sugar and add to butter, beating them well together. Beat in egg yolks with 2 spoonfuls flour. Combine cream of tartar and baking soda with remaining flour and cornstarch, and add them gradually to the other ingredients along with the milk. Whip egg whites to a stiff froth, and fold them quickly and lightly into the cake mixture. Bake in a lined cake tin in a slow oven (350°F.) for 1 to 1 ½ hours, or until cake is well risen and from to the touch. Turn out of the tin and allow to cool. Then cut the cake in 3 or 4 layers; spread each layer with chocolate icing and assembled cake again. Ice with chocolate icing and decorate with preserved fruits or finely chopped pistachio nuts.
