Jicama is a crunchy, slightly sweet root vegetable with a crisp texture and thin brown skin. Typically peeled and sliced or julienned, it's enjoyed raw in salads, slaws, or as a snack with lime and chili. It also works cooked in stir-fries or soups for added texture and mild flavor. A good source of fiber and vitamins, jicama stores well refrigerated for several weeks.
