1 cup butter, cold and cut into small pieces
½ cup fruit sugar (regular granulated sugar is fine)
¼ lb (1 cup) unblanched almonds (skins on), ground
1½ cups all purpose flour.
Mix as dough. (Mix altogether in a blender/food processor until it sticks together.)
Scoop level 1.5 tsp (1/2 T) and form a ball. (THIS is the important part! Any larger and the cookies just spread out and lose their shape before they cook through.)
Gently shape into a slight 'log'; place on a cookie sheet and shape into crescents.
Bake @ 325 °F for 20 - 23 minutes, until 'just' a bit golden on the tips.
When baked, slide onto brown paper. Coat in vanilla sugar while warm.
(Put sugar into small bowl with shallow sides to make it easier to turn cookies to coat.)
Makes about 6 dozen cookies.
