If you're shopping for couscous in the supermarket, you'll find it alongside products like oats, rice, and barley. However, couscous is technically not really a grain like these products.

Grains are seeds or fruits that come from various cereal crops, like rice and quinoa. When harvested, grains may be milled, but there are no extras added in.

Couscous, on the other hand, is produced using flour and water, resembling a flour-based product such as pasta rather than a grain.
