Rice is a type of swamp grass which produces the most common cereal grain eaten by humans. The seeds of the rice plant can produce both brown and white rice; when the outer husks are removed from the seeds this creates brown rice, by removing the rest of the husk and the germ white rice is produced. Rice can be ground into flour, made into a variety of beverages including sake and rice milk, but is most commonly boiled or steamed to be eaten.
