3 c  Sugar
1/2 lb Butter
1/2 c  Vegetable Shortening
6    Eggs; Large
3 c  Cake Flour; Sifted
7 oz Fresca; Soda Pop
1 ts Baking Powder
1 ts Vanilla Extract
1 tb Lemon Rind; Grated
1 tb Lime Rind; Grated

ICING
2 Egg Whites; Large
1 c Sugar
1 tb ;Water
2 tb Maraschino Cherry Juice
1 tb Light Corn Syrup
1/4 ts Cream Of Tartar
10 Maraschino Cherries; Chopped

Preheat oven to 350 degrees F. Cream together sugar, butter and
shortening. Add eggs, one at a time, beating well after each addition. Add
flour and Fresca alternately. Add baking powder and when mixture is fully
creamed, add vanilla and fruit rinds. Pour into greased and floured 9 X
13-inch Cake Pan. Bake 1 hour or until cake tester comes out clean.
FROSTING: Mix all ingredients except cherries and beat constantly while
heating in the top of a double boiler. When thoroughly mixed, thick, and
spreadable, frost cake. Decorate top of cake with chopped maraschino
cherries. NOTE: Since Fresca is available only in limited areas if at all,
7-up may be a good substitution, or any lemon-lime drink. Also, since the
problem with the cherries has been resolved with a different food coloring,
you may use the new ones or use gum drops instead for the garnish. Syrup
from a can of dark cherries might be substituted for the Maraschino cherry
syrup.
