Chocolate-Espresso Chiffon Cake

Separate eggs, discarding 3 of the yolks or saving for another use. Let eggs stand at room temperature 30 minutes. Preheat oven to 325 degrees F. Dissolve espresso in water; set aside.

In large bowl stir together flour, sugar, baking powder, and salt; make well in center. Add oil, the 5 egg yolks, dissolved espresso, and vanilla. Beat on low until moistened; beat on medium-high 4 to 5 minutes or until satin smooth. Stir in grated chocolate.

Wash and dry beaters. In 4-quart bowl beat egg whites and cream of tartar on medium-high until stiff peaks form (tips stand straight). Pour chocolate batter in thin stream over surface of whites; fold to blend. Spoon in ungreased 10-inch tube pan.

Bake 60-70 minutes or until top springs back when lightly touched near center. Invert pan to cool. Carefully loosen sides; remove from pan. Serve with Espresso Whipped Cream. Makes 14 servings.
