An HEIRLOOM treasure from China, sometimes called Roseheart or Red Meat Radish, the Watermelon Radish has a ball-shaped root that is about 4 inches in diameter. Deep green shoulders fade to a bright white skin and finally a bright rosy, red flesh reminiscent of a summertime watermelon. Crispy, and with a mild, sweet flavor, it lends itself well to salads, garnishes and your favorite Asian dishes.
