The potato is a starchy, tuberous crop. Potatoes have become a staple food in many parts of the world and an integral part of much of the world's food supply. Potatoes are the world's fourth-largest food crop, following maize (corn), wheat, and rice.
Over 99% of the presently cultivated potatoes worldwide descended from varieties that originated in the lowlands of south-central Chile, which have displaced formerly popular varieties from the Andes.
Potatoes are prepared in many ways: skin-on or peeled, whole or cut up, with seasonings or without. The only requirement involves cooking to swell the starch granules.
