1/2 cup Cornstarch
175 g Butter
1/2 c Powdered sugar
1 c Rice flour
Sugar (for sprinkling)
Sift together cornstarch, sugar and rice flour. Add butter, mixing with hands until a soft dough forms. Chill for one hour in refrigerator. Shape the chilled dough into 1 inch balls. Place balls about 1 1/2 inches apart on greased baking sheet. Flatten balls with a lightly floured fork. Bake at 300 degrees F for 20-25 minutes or until edges are lightly browned.
You can also roll the balls before flattening in finely chopped nuts, make an indentation in the top of the ball and add a small amount of jelly. Then flatten and bake.
