21⁄4 cups sifted cake flour

11⁄2 cups sugar

3 tsp baking powder

1 tsp salt

1⁄2 cup neutral oil

5 egg yolks

2 tsp grated orange peel

1 tsp grated lemon peel

1⁄2 cup fresh orange juice

1⁄4 cup water

2 tsp vanilla

1 cup egg whites (7 or 8)

1⁄2 tsp cream of tartar

CITRUS FROSTING

2 tsp grated orange peel

2 egg yolks

Orange juice

1 tsp grated lemon peel

1 Tbsp fresh lemon juice

1⁄4 tsp vanilla

6 Tbsp softened butter or margarine

1 lb. confectioners’ sugar

Combine yolks with enough juice to yield 1⁄3 cup. Combine all ingredients in a bowl. Beat until smooth and of spreading consistency.

Sift together dry ingredients in a large bowl. Make a well in the center; add oil, egg yolks, orange and lemon peel, orange juice, water, and vanilla. Beat until smooth. Beat egg whites until frothy; add cream of tartar. Continue beating until whites hold very stiff peaks but are not dry. Carefully fold in the egg yolk mixture until just blended. Pour into a 10-inch tube pan. Bake at 325 F for 50 to 55 minutes; increase heat to 350 F and continue baking for 10 to 15 minutes. Remove from the oven and invert immediately on a wire rack. Cool completely before removing from the pan. Spread with the citrus frosting.
