Mom's Shortbread

1 lb softened butter (Must be butter not marg!)
1 c Confectioners sugar
3 1/4 c flour
1/2 c Rice Flour
1/2 tsp Baking powder
3 TBSP corn starch
1/2 tsp salt

Mix butter and sugar until fluffy
add sifted dry ingredients and mix until crumbly then knead with hands until smooth and soft. Form into balls about the size of a golf ball (not quite that big) and press with a cookie press (mom uses a crystal wine glass with a nice pattern if you don't have a cookie press)
Bake at 350* for 8 to 10 minutes just until edges start to turn golden.
