Aside from its use in (Northern)Johnnycakes, it seems that white cornmeal is used almost exclusively in ' the South' and also that the South uses almost exclusively white cornmeal.(BIG area, I know.....). So I'm guessing that white cornmeal is made from white corn ? and white corn was the norm in the South, which was settled before the Midwest (maybe yellow corn was a later development/popularity?)
Plse educate me on this if you can! Thank you.
