9 eggs - separated
1½ cups sugar
1½ teaspoons vanilla
Juice and rind of 1/2 lemon
Juice and rind of 1/2 orange
1/2 cup potato flour (I use corn starch which is not kosher for Passover, but works just fine)
1/2 cup matzoh cake flour (available most places around Passover)
Beat whites with a pinch of salt to peaks, but not dry. Gradually add 1 1/2 cups sugar. Beat until sugar is well beaten in. Beat yolks until creams and light colored. Beat in vanilla, juices and rinds.
Mix 1/2 cup potato flour (or corn starch) and 1/2 cup matzoh cake flour and fold into beaten whites.
Bake in a tube pan at 350 degrees for 40 minutes then 325 degrees for about 15-20 minutes more.
Although my grandmother usually served this with fruit, you can also top it with whipped cream, a glaze of orange or lemon juice mixed with powdered sugar, or (if you happen to have some have some) lemon curd.
