@ElwoodBlues It uses oats, when blended it becomes oat flour.

@Sweet00Lullaby Actually, now it occurs to me; in our area we can get steel-cut oats, rolled oats, or quick oats. I think quick oats would break up the most during blending, so is that the form of oats that should be used?

@ElwoodBlues Steel cut and rolled oats would work as well.
