5 eggs, separated (at room temperature)
3/4 c. flour
1/4 tsp. salt
4 tbsp. cocoa
1 c. sugar

Beat yolks and whites separately each for 5 minutes. Sift together flour, salt, and cocoa. Sift separately the sugar. Fold yolks into the whites very slowly. Add sifted sugar. Then slowly add the flour mixture.

Grease and flour a cake pan. Bake for 15 minutes at 350 degrees. When done, immediately turn on a towel that has been sprinkled with powdered sugar. Roll up gently while warm and refrigerate until cool. Unroll and fill with ice cream or whipped cream, re-roll and freeze. Serve in slices.
