1-2/3 c. sifted cake flour
1 tsp. salt
1 tsp. baking powder
12 egg yolks
1/2 c. hot water
1-1/2 tsp. vanilla (or lemon extract)
1 c. sugar
One hour ahead of time set out eggs. (Save egg whites for other use, such as Angel Food Cake below) Sift flour, salt, and baking powder three times. Beat egg yolks at high speed until slightly thick. Gradually add hot water. Beat about 10 min. until very thick and light. Beat in flavoring. Add sugar, 1 tablespoon at a time, beating constantly. Fold in flour mixture, in fourths, just until blended. Bake in 10" ungreased tube pan at 375 deg. for 40 minutes. Invert pan. Leave upside down until completely cold.
