Aunt Ida'S Passover Sponge Cake - cooking recipe

Ingredients

12 eggs, separated
1 cup matzo meal
1/2 cup potato starch
1 tablespoon oil
2 cups sugar
1/2 teaspoon salt
1 tablespoon vanilla extract
1 cup orange juice

Preparation

Sift cake meal and potato starch together and set aside.
Add oil and vanilla to egg yolks.
Add sugar and salt while beating.
Continuing to beat, add orange juice alternately with sifted dry ingredients.
Beat some more until creamy.
Beat egg whites until stiff, and fold into egg yolk mixture.
Pour batter to about 1 1/2\" from the top of an ungreased 10\" tube pan (an angel-food cake pan, with removable sides.) Bake at 325 degrees F.
for 50-60 minutes.
(There will be enough batter left over for an additional 8\" or 9\" round cake.) Invert to cool (important so cake won't collapse!).
