Grain-Free Gluten Free Flour Blend

Here is the flour blend I use to make yeast bread, quick breads, cookies, cupcakes, etc.  It is my all-purpose baking flour since I'm allergic to almost all grains.  I blend it ahead of time using a whisk to get it evenly distributed, then I store it until I use it.  I do it by weight with a scale so I don't know the cup measurements but here it is:

Potato Starch 24 oz
Gar/Fava Bean Flour 13 oz
Tapioca Flour 5 oz
Coconut Flour 2 oz (I like the lightly sweet scent this adds)
Mesquite Flour 1 oz (I like the slightly chocolatey scent this adds and the color)

Sometimes I used to also add one of these GRAINS, but I no longer do:
Amaranth Flour 2 oz
OR Wild Rice Flour 2 oz

When all the eaters are able to use nuts, sometimes I'll use about 2/3 volume of this GF flour in recipes and the remaining 1/3 volume I'll use almond meal.  I've done this in yeast breads, quick breads, cookies and cupcakes.

I hope someone finds this useful!
