1 lb. almonds
1 lb. confectioners' sugar
1 tsp. almond extract
3 egg whites, very slightly beaten

Blanch almonds and remove skins. Work almonds through a fine food grinder twice or work in a blender or food processor. Mix thoroughly with sugar. Add extract. Stir in egg whites to make a firm paste; knead for 5 minutes with hands to draw out the oil in the almonds.
