Hello! I recently got a new variable speed Vitamix with the dry pitcher, and I'm trying to grind some dry hot cereal out of organic brown rice so that I'll save money over buying it pre-ground from the store. I'm trying to make it about the grain size of coarse polenta, but regardless of what speed I use, it's either too fine, turning it to flour, or too coarse, just barely chopping up the grains of rice to half or three quarter size. I'm not even using it on the eight setting!
What am I doing wrong? What do I need to do to get this to a hot cereal grain size??
