Jicama (pronounced hick-ah-mah) is a root vegetable native to Mexico. The plant grows as a vine that can reach up to 20 feet in length. It has white or blue flowers and pods that resemble something like a lima bean. Interestingly enough, the entire plant is toxic except the root. This root has a tough brown skin but when you peel that away, it opens to a milky white, juicy flesh that has a flavor similar to an apple with the crisp texture of a raw potato.
