3/4 c Matzo meal
3/4 c Potato starch
1/2 ts Salt
6 Egg yolks
1 3/4 c Sugar
Recipe
Mix the matzo meal, potato starch and salt together.
Beat yolks until thick; gradually add the sugar, beating until lemon colored. Add matzo-meal mixture alternately with the orange juice.
Fold in the walnuts and lemon rind, and then the egg whites. Turn into a 9-inch tube pan.
Bake in a 325 degree oven 1 hour or until browned and the cake shrinks away from the sides of the pan.
