Ok...have you got a recipe for that? I have ground pintos into flour several times, but only ever used them for quick re-fried beans or in soups.
The flour is only milled from dry beans, make sure you have a good mill, if you only have a grain mill then you will have to run the dried bean through a blender first before it can be milled in the smaller grain mills also note, under cooked bean flour can be toxic to some people, I have never known anyone getting sick from the flour, it was something my Grandmother told me.
4 cups of flour for each pound of beans, most beans can be milled into flour. Different recipes for different bean flours, tons of recipes are out their using these types of flours. The wife has a recipe for Cherokee bean bread, I couldn't find it at the moment. You can also cook the pinto beans then mush them then add to muffin recipes, white bean flour can be used to to cut back on wheat flour if your low say 50/50 taste will be affected. if you are gluten intolerant then learn to use bean flour
You can also mill peas, add a little salt and bag to make a quick hot thick trail drink, add a little honey to sweeten
