Because they can be made using matzoh cake meal instead of flour, sponge cakes have long been favorite Passover desserts. This recipe, which is brought to us by senior producer Lisa Wagner, was first prepared by Lisa's grandmother Rea.
Martha Stewart Living, June 2003
- Yield Makes one 10-inch cake
- 2/3 cup matzo cake meal
- 1/3 cup potato starch
- 1/4 teaspoon salt
- 9 large eggs, separated
- 1 cup granulated sugar
- Juice and zest of 1/2 orange
- Juice and zest of 1/2 lemon
- Passover Powdered Sugar (http://www.marthastewart.com/261216/passover-powdered-sugar)
- Heat oven to 325 degrees with rack in center. Whisk together matzo cake meal, potato starch, and salt; set aside. In the bowl of an electric mixer fitted with the whisk attachment, beat yolks and 3/4 cup granulated sugar until thick and pale yellow. Gradually add dry ingredients, alternating with juice and zests.
- In the clean bowl of an electric mixer fitter with the whisk attachment, beat egg whites until foamy. With machine running, gradually add remaining 1/4 cup granulated sugar and the salt. Continue beating until soft peaks form. Remove from mixer. Gently but thoroughly, fold egg whites into yolk mixture in two additions.
- Pour into a nonstick 10-inch tube pan. Bake until golden, about 1 hour. Remove from oven, and invert onto a narrow necked bottle. Let stand until cool, about 1 hour, before removing pan. Will keep covered at room temperature for up to 3 days. Just before serving, dust with powdered sugar.
