Right now this list is for the San Francisco Bay Area — if I get enough comments with information for your town and state I’ll build another national section

Berkeley Bowl (West) 920 Heinz Ave, Berkeley, CA     Probably the same as Berkeley Bowl East, but I haven’t been there recently to check

Bombay Spice House, 1036 University Ave/10th st & Milan, 900 University/9th st, Berkeley, CA

Bombay Spice house has packaged items, Milan has both packaged and bin items.  Indian stores have ground lentil and bean flours you can’t buy anywhere else.

At WebMD, in “How Save is Imported Food?”, India was listed as second to China in FDA rejected shipments.  None of these flours are organic.  The foods most commonly rejected are: vegetables and vegetable products; fishery and seafood products; spices, flavors and salts; and candies.  But not flour, whole lentils, and beans, so I think these are probably okay — they’re certainly a lot less expensive than most grocery stores.  If you’re going to mill the softer legumes in a coffee & spice mill, you could soak them in water a while, drain, and wait for them to dry out a bit.
