Cornmeal is a coarse kind of flour made from dried kernels of maize. You can sprinkle cornmeal on a pizza pan to keep the crust from sticking, or cook it with water to make polenta.
Grind corn into meal and you get cornmeal, a versatile ingredient that's used in staple foods all over the world. In the U.S., particularly the South, cornmeal is used for grits, fritters, hushpuppies, and cornbread. Mexican cuisines add lime and make masa, the base of tortillas and tamales. Corn congee is a common dish made from cornmeal in several East Asian countries, and in Barbados, cornmeal-based cou-cou is part of the national dish.
