Jicama is a large, bulbous root vegetable. A bulb may weigh one or two pounds and has a rough 'n' tough brown skin which should be peeled before eating or cooking.
Flowers, either blue or white, and pods similar to lima beans, are produced on fully developed plants. Several species of jicama occur, but the one found in many markets is Pachyrhizus erosus. The two cultivated forms of P. erosus are jicama de agua and jicama de leche: both named for the consistency of their juice.
