Cornmeal is a meal (coarse flour) ground from dried maize (corn). It is a common staple food, and is ground to fine, medium, and coarse consistencies, but not as fine as wheat flour. In the United States, very finely ground cornmeal is also referred to as cornflour. However, the word cornflour denotes cornstarch in the United Kingdom, where cornmeal is not widely available.
There are different types of cornmeal.
Steel ground yellow cornmeal, which is common mostly in the United States, has the husk and germ of the maize kernel almost completely removed. It is conserved for about a year if stored in an airtight container in a cool, dry place.
Stone-ground cornmeal retains some of the hull and germ, lending a little more flavor and nutrition to recipes. It is more perishable, but will store longer if refrigerated. However, it too can have a shelf life of many months if kept in a reasonably cool place.
Blue cornmeal is light blue or violet in color. It is ground from whole blue corn and has a sweet flavor. The cornmeal consists of dried corn kernels that have been ground into a fine or medium texture.
