Steps
THIS RECIPE DOESN'T MAKE SENSE. THERE'S CONFUSION BETWEEN SEPARATED EGG YOLKS AND WHITES.

Sift potato starch and cake flour together. Beat 7 egg whites with 1/2 cup sugar. Combine flour mixture, remaining sugar, orange juice, orange rind, salt and bananas in a large mixing bowl. Fold in yolk mixture. Bake at 325° for one hour. Invert onto rack to cool.
