A vegetable with an oval bulbous white base, fennel has the delicate, light, sweet flavor of anise and the texture of green cabbage. Its celery-like stems have wispy bright green tops.
When buying fennel, look for clean, crisp bulbs with no brown spots. Other signs of a fresh fennel bulb are bright green color and tops that are not wilting.
Remaining feathery greens from fennel can be used for seasoning soups and salads.
