Italian Pine Nut Cookies

1. Add almonds to 2 beaten egg whites and stir. With a slotted spoon, remove almonds to a blender or food processor and blend to a smooth paste. Transfer to a bowl and stir in sugar and orange juice concentrate. Shape dough into walnut-sized balls. Place on a parchment lined baking sheet 1 inch apart and flatten to a 1/4 inch thickness with the bottom of a glass. Brush tops with beaten egg white and stud with pine nuts in an attractive design. Allow to stand at room temperature for 2 hours.
