So, for us foreign devils, grits are dried corn kernels? And once cooked (by boiling in water, I'm assuming) what do you do then?
Well, they are not whole corn kernels either. They are chopped up dried white hominy corn, dried, and boiled in water. They resemble Cream of Wheat or Malt-O-Meal in consistency.
What do then is eat them. Some people put butter and salt and pepper on them, or sugar and butter, or various other ways to dress them up.
Almost no one just eats them plain.
