Couscous is made from taking coarsely milled grain, dampening it, rubbing it into tiny granules and lightly flouring the granules so they don't stick together. The couscous is then dried and stored. Couscous can be made from most grains, but is usually made from wheat, sorghum or quinoa. It is traditionally cooked by slowly steaming it over a cooking stew until it is light and fluffy. Modern couscous has been pre-steamed and then dried, and can be prepared by covering it in boiling water or a stock. Pre-steamed couscous can be cooked in about 5 minutes.
