You know, I've always wondered (well maybe not always, but certainly since I've gone all locavore) why there is such little "corn" culture in our part of the world. Sure, we go ga-ga for sweet corn, but that's pretty much it. We don't seem to use cornmeal/grits/polenta generally, or at least a lot. Someone once ventured, when I said this, that it was as a consequence of all that Midwestern corn being used for ethanol, high fructose syrup and animal feed. That we do not consider corn food. Given our high affection for sweet corn, I'm not sure I buy that, but I'm not sure. Why are there not more local grits.
OK, you want an answer not a problem, and I do have one for you. Ted's Grains is a small outfit near DeKalb, that creates local ground stuff including something like polenta or grits. It's local and therefore good, right, but I will warn that Ted's is heavy on the corn end of the scale, not as smooth, so to speak as your standard grits. Heritage Prairie usually sells Ted's grains at Green City Market. Also, at GCM, Three Sisters sometimes has ground corn too.

If you want to take a short road trip, [url=http://www.elkhartcountyparks.org/properties_locations/bonneyville_mill.htm]Bonneyville Mill in Elkhart, IN is a really neat place, with a water driven stone wheel a-grindin' corn and other items.
