Yes. I make oat flour out of raw oat groats and almond flour out of the dehydrated pulp I strain out when I make almond milk. I just use the dry mix container on my VitaMix blender and I’m happy with it, though I don’t feel like it’s super-fine. However, a friend of mine regularly mills all of her own flour and has raved about the Vario mill by Schnitzer for years. It’s really expensive, but apparently, it’s amazing.
Do you mill your own flour?
