The Watermelon radish's flesh is white closest to the exterior becoming bright circular striations of pink and magenta, hence the watermelon reference. Its flesh is tender-crisp, succulent, and firm. Its flavor is mild, only slightly peppery with almond-sweet notes. Depending on when harvested, Watermelon radishes can range in size from golf ball to softball. Look for Watermelon radishes with smooth skin free of deep cracks and for an exceptionally pink interior look for radishes with pink taproots.
