1 1/4 c. sifted flour
1 c. sugar
1/2 tsp. baking powder
1/2 tsp. salt
6 egg whites
1 tsp. cream of tartar
1/2 c. sugar
6 egg yolks
1/4 c. water
1 tsp. vanilla

Sift flour, 1 cup sugar, baking powder and salt in a large mixing bowl. Beat egg whites until frothy. Add cream of tartar. Gradually beat in 1/2 cup sugar. Beat until whites form stiff peaks. In a small bowl, combine egg yolks, water and vanilla. Add dry ingredients. Beat at medium speed for 4 minutes or until mixture is light and fluffy. Fold yolk mixture gently but thoroughly into beaten egg whites. Turn into an ungreased 10-inch tube pan.

Bake at 350°F about 45 minutes. Use light icing or dust with powdered sugar.

If cake begins to brown too much while baking, cover with foil for awhile.
