<<Disclaimer: Verify this information before applying it to your situation.>> Two friendly folks wrote to me about bean flour. One said that the Authentic Foods bean flour is a combination of garbanzo and broad beans, so I could probably substitute garbanzo bean flour -- I know I can get this at my local HFS in their Indian foods section, although there's no way to then find out how pure the product is since it's imported from India. Another person suggested Bob's Red Mill bean flour, and in fact I asked my HFS to order it for me. I'm writing again now to ask, does anyone know how careful Bob's Red Mill is about keeping their g-f flours clean? Does anyone have Bob's phone number? (I didn't think about this problem until after I'd ordered a bag at the HFS.) Thanks again.... Muriel Kranowski Blacksburg, Virginia
