6 cups brown rice flour

2 cups sorghum flour

2 heaping cups tapioca flour (not homeground, I found this stuff for dirt cheap at an Asian market)

2 1/4 cups cornstarch (one of those nifty cans)

1/2 cup arrowroot

4 tsps (one was heaping) xantham gum

Used this flour to make chocolate chip cookies — yum!!!
