In 1994 I was diagnosed with celiac disease, which led me to create Celiac.com in 1995. I created this site for a single purpose: To help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives. Celiac.com was the first site on the Internet dedicated solely to celiac disease. In 1998 I founded The Gluten-Free Mall, Your Special Diet Superstore!, and I am the co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.
The following is a recipe for a Sponge cake made with potato starch and it is wonderful served with fresh fruit (sliced strawberries with a little sugar) and a whipped topping or ice cream.
1 ½ cups sifted sugar
1 ½ teaspoons grated lemon rind
3 tablespoons lemon juice
1 full cup potato starch
dash of salt
Separate the eggs. Using an electric mixer beat the egg whites until stiff and set aside. Beat the egg yolks for 2 min. at high speed. Add the lemon juice, sugar and lemon rind and beat another 2 min. at medium speed. Gradually add the sifted potato starch and continue mixing at medium speed an additional 2 minutes.
Fold the beaten egg whites gently but thoroughly with the egg yolk mixture. Place in a non-greased 2-piece 10 tube pan and bake in preheated 350 degree F for 55-65 minutes or until cake springs back when firmly touched with fingers. Invert pan and cool thoroughly before removing from pan (I use a wine bottle and to prop up the cake to keep from pressing the top down).
