When I first got my mill, I had a bag of corn meal on my shelf that was sitting, unused because it was too coarse. I put it through the mill on the finest setting and it milled it quickly and perfectly. That night, I cooked cornbread with the cornmeal that I had refused to use because it was so coarse. That is only the beginning of my journey. I have milled cornbread, wheat and spelt, all without problems. Everything comes out perfectly.
