Gluten Free Flour Blend (updated recipe)

Since the last time I posted the gluten free flour blend we use, my hubby has played around with it some more and come up with a blend we absolutely love. It's not too far off from the old recipe though. This is also for a double batch. We store it in gallon ice cream containers at the back of the fridge and just pull it out when we need it. We've had great success using it in non-gluten free cookie recipes. For the brown rice flour, we use a grain mill that has never been used with wheat and we grind it ourselves. We use Lundberg Farms Organic Brown Rice that comes in 20 lb. bags at Costco.

Gluten Free Flour Blend

11 cups brown rice flour
1 1/2 cups sorghum flour
6 cups corn starch
2 cups potato starch
3 cups tapioca flour
1 cup potato flour
1 1/2 cups sweet rice flour
4 TB xantham gum

Blend all ingredients really well and store in airtight containers in the fridge.
