<<Disclaimer: Verify this information before applying it to your situation.>> Hi Am wondering about the purity of Arrowhead Mills brand rice flour. There are gluten free recipes (with gluten free in the title) on the packages. I know they manufacture other types of flours also, so I'm wondering about the purity. Can't find EnerG rice flour locally and I ran out!! Need some to tide me over until my new shipment. thanks in advance. kris wichita, KS
