The United Nations designated 2008 as the International Year of the Potato. We’re sure you know what a potato is, but the official line coming from FAO.org informs us that it is a “herbaceous annual growing up to 40 inches tall, producing a tuber—also called potato—that is so rich in starch that it ranks as the fourth most important food crop in the world, after maize, wheat and rice.” Very select company then.
