So, I've been experimenting again. This time with flours. My goal is to find other flours that work in the recipes I use most. I rely mostly on chickpea flour and, in some sweets, sorghum flour. I mix those in with tapioca and potato starches.
I bought some quinoa grain at $2 a pound and some amaranth grain. Mind you, quinoa flour sells for $6/1.5 lbs. Amaranth, just as much.
Anyway, I threw the grain in my coffee grinder on a fine setting and let it rip. Worked out very well. I made my pancake recipe using the quinoa flour -- turned out perfectly. The amaranth is courser and I haven't used it yet.
This opened my eyes to the world of grinding. Grinders of all types are sold. You'll want a stronger one if you plan to grind corn and nuts, etc. There's a nice comparison of grinders at the Walton Feed website.
It's yet another economical way -- in the long run -- to stick to the GFCF diet.
