Jicama is a root vegetable that resembles a very large potato or brown turnip. When eaten raw, it has a mild flavor with a crisp texture, not unlike an unripe pear. Eat it raw, sprinkled with salt and lime juice, or use it as a vehicle for dips from ranch dressing to hummus. Jicama may also be used in a stir-fry to create a crunch similar to water chestnuts or sauteed on its own for a side dish. A ½ cup serving of jicama counts toward your 2 to 3 cups of vegetables adults are recommended to eat each day.
