Corn-Free Powdered Sugar: The ratio is 1 cup regular sugar to 1 tablespoons arrowroot starch or tapioca starch
Mix in food processor or uncontaminated coffee grinder until it is fine and powdery. Store in an airtight container.
Note: sugar often contains corn or corn derivatives. Please be sure to contact the manufacturer to verify if your sugars contain corn or not.
Corn-Free Baking Powder: I use featherweight, but you can also make a corn free substitute.
1 tsp baking soda
2 tsp cream of tarter
1 tsp tapioca starch/arrowroot powder
