Cornmeal is ground up corn. It is not to be confused with cornstarch or corn masa. Both cornstarch and finely-ground cornmeal are sometimes called cornflour; this is thus a bad term to use. Cornmeal is an essential ingredient use in Jamaica to make, cornmeal pudding, cornmeal porridge, cornmeal dumpling, turn cornmeal, and festival. Cornmeal which has been leached with lye is called corn masa. There are two types of cornmeal in Jamaica, coarse and refined. The coarse ones are cooked then give to dogs (dog feeding) while the refined ones are used in recipes.
