Jicama plant grows as a vine and is actually a legume or member of the bean family. The root of the plant tastes like a cross between an apple and a potato. It has the texture of water chestnuts. Store these roots in the refrigerator until ready to use. Peel off the brown shell and any fibrous material directly under the skin. These fruits can be eaten raw in salads or served with dip, or cooked in stir fry, roasted or added to soups and stews. Jicama is also a good source of vitamin C.
