All parts of the radish plant are edible. Choose firm radishes with fresh, springy leaves. The leaves should be cut from the roots for storage, as the leaves continue to draw water from the roots.
Both the roots and leaves need to be washed thoroughly before they are prepared for serving. The round roots can be sliced and eaten by themselves or tossed in salads. If they are daikon or mooki radishes, the roots can be used in stir fries. The leaves are tasty when tossed in a salad with other salad greens. Both the roots and greens of the radish plant have a peppery flavor.
