A simple way to obtain gluten free flour is to use Bob’s Red Mill Gluten-Free All-Purpose Flour, which is sold in bulk at the Missoula Community Food Coop.
We like to use guidelines from 1,000 Gluten Free Recipes to make a sorghum blend. We buy the tapioca and potato starch in bulk from the Coop and packages of the sorghum flour. Everything is cheaper in bulk! We then store the mix in jars.
One package of Bob’s Sorghum Flour (4.5 cups) or 35%
4.5 cups potato starch or 35%
3 cups tapioca flour or 30%
