you can find unsweetened 100% cranberry juice at trader joes or a natural food store. these are an equally tart variation on lemon bars. next time i would like to try and make them with a fresh cranberry puree.

2 cups flour
1/2 cup powdered sugar
zest of 1 orange
2 cups sugar
3/4 cup unsweetened cranberry juice

1. preheat oven to 350 degrees. combine butter, flour, powdered sugar and orange zest just until dough begins to come together.
2. pat mixture into 9x13 inch baking dish. bake 20 minutes until just starting to turn golden. cool completely.
3. combine sugar, cranberry juice, flour, baking powder and eggs. pour over cooled crust.
4. bake 25 minutes at 350 degrees. cool completely and cut into squares. sprinkle with powdered sugar.
