I checked the back of the Bob's Red Mill All Purpose Baking Flour.

The ingredients a Garbanzo Bean Flour, Potato Starch, Tapioca
(Manioc) Flour, White Sorghum Flour and Fava Ben Flour.

They also have a guide on the back as to how much Xanthan gum to add
in for
each type of baking.

I checked the www.bobsredmill.com site and they have 462 gluten free
recipes including soups, breads, breakfast cereal, pretty much
anything.

I had pretty much given up baking because it is so high carb but a
couple of these recipes look very interesting to me.

I'm still going to do some more research on the manioc (tapioca)
flour.
