Cornmeal is flour ground from dried corn, and is a common staple food. In the United States it is also called cornflour. (In the United Kingdom, cornflour is used to mean cornstarch.)
Steel ground yellow cornmeal, common mostly in the United States, has the husk and germ of the maize kernel almost completely removed. It is conserved almost indefinitely if stored in an airtight container in a cool, dry place.
