Mesquite Flour - Grinders and Recipes

Just made my first mesquite flour. Made a chocolate chip cookie recipe. I think I did something wrong, because they were totally flat but SO DELICIOUS! I would highly recommend it to anyone gluten free or who has mesquite trees in your neighborhood!

Couple of questions:
1. I have used a food processor to grind it, but am looking at getting a grain mill. Does anyone know if a grain mill would work on mesquite beans? I've never had a grain mill so don't totally know how they work.

2. Anyone have recipes for mesquite flour. I'm supposed to be gluten free and would love some great sourdough bread or other recipes for mesquite flour.

I live near a place that grinds Mesquite flour.  I though they might have a website with recipes though I did not find it.

I did find a website that said to use Coconut Flour recipes (1:1).

I hope this helps.
