Thank you Deb but I'm not quite there yet. I had previously read the article you directed me to but aside from telling what not to use 'fine' for there is no indication as to what one can do with it.
"Packages labeled polenta mean that the grind of the corn is appropriate to make the polenta dish, but you can substitute regular medium or coarsely-ground cornmeal instead. Don't use finely ground cornmeal or corn flour which have too fine of a consistency and will give the finished dish a pasty texture."
My issue arose when my partner, not a cook, purchased 'fine' and I'm now after a use other than as an ingredient to use in lieu of plain flour when frying or dusting cake tins etc. Perhaps that's all it's good for but I can't seem to establish this via my cook books or the net.
