 Sift together flour, granulated sugar, baking powder and salt into
 bowl. Make well in center and add water, oil, egg yolks, grapefruit
 juice and 1/2 teaspoon lemon peel. Beat until very smooth. Beat egg
 whites with cream of tartar until stiff but not dry. Gradually pour
 egg yolk mixture over egg whites and fold in gently until just
 blended. Do not stir. Turn batter into ungreased 9-inch springform
 pan and bake at 350F 30 minutes, or until top springs back when
 touched lightly with finger. Invert onto rack and cool thoroughly.
 To make frosting, beat cheese until fluffy. Add lemon juice and 1
 teaspoon peel. Gradually blend in powdered sugar and beat until well
 blended. Stir in food color. Crush enough grapefruit sections to
 measure 2 teaspoons and blend into frosting.
 Loosen edges of cake carefully and remove from pan. With serrated
 knife cut cake crosswise to make two layers. Fill with part of
 frosting and some of grapefruit sections. Spread top and sides of
 cake with frosting and decorate with remaining fruit sections.
