1-3/4 cups flour
1 cup finely chopped pistachios
1/3 cup sugar
Combine the above and then add 1 cup (2 sticks) of cool butter and blend until a dough. Roll out on a lightly floured surface and cut out shapes of your choice. Put on a lined cookie sheet and bake for 15-18 minutes at 325 degrees or until just starting to brown on the edges.
If you wish, after the cookies are cool, you can dip one half in melted white chocolate and sprinkle more chopped pecans on the chocolate and then let set. These freeze well.
