1 1/2 tablespoons tapioca starch/flour or potato starch in measuring cup,
plus enough granulated sugar to make 1 cup.
Process mixture in a blender on high speed for 45 seconds or until powdered. (Here is where you will love the Blend Tech) If you have a regular blender, do it in one minute intervals. Blend, rest, Blend, rest, blend...you get the idea...we don't want to burn out our machines. Some machines may take longer to process to be fine enough.
If your machine gets warm....stop and wait until it cools down.
Store in an airtight container.
