• 1 cup unbleached cane sugar
• 1 tablespoon cream of tartar or 1 tablespoon potato starch or 1 tablespoon tapioca starch or 1 tablespoon arrowroot

1. Blend ingredients in a blender until a fine powder forms.
2. Be sure to choose a sugar that doesn't contain corn like C&H pure cane sugar, Dixie Crystals or Domino sugar.
3. If you use cream of tartar, it will come out tasting tart.
4. Use only if you are making lemon or lime icing or something similarly tart or sour.
