There are so many options when it comes to flours. I really try to stay away from bleached white flours because of how nutrient depleted it is. There are so many more options out there that make beautiful baked products!
I try to grind all the flours once a month because of what a mess it makes. But then store them in gallon size bags- all ready to re-fill my tuba wear during the month.
Here are some optional flour ideas:
Pinto beans (dried)
Most Dried Beans
I have a Kitchen Mill Grinder and it will grind almost anything!
