I was never acquainted with corn meal mush until introduced to it by my late husband's southern roots. Back in the day I used to cook up potfuls of various hot cereals, many of which I can't even remember now, if they still exist. There was ralston, maltex, creams of wheat or rice, oatmeal, and corn meal mush. I was familiar with corn bread and so had a round container of corn meal on the shelf, but learned after the fact that it could also be boiled as a hot cereal. What I haven't seen mentioned on this forum yet, is fried cornmeal mush. I learned to make that, with the suggestion and instructions from hubby, even later, one day when we had leftover corn meal mush.
Often I would offer leftover cooked cereals, topped with maple syrup, to the horses. That was always a big hit!
