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.
Jicama is excellent raw and is sometimes eaten plain. It can also be used as a substitute for water chestnut in Chinese dishes, in which case it should be thrown in right before serving. The roots also appear in stews, juiced drinks, stuffings, and a variety of other recipes.
