Both the base and stems of Florence fennel can be cooked by braising or roasting, which make it sweet and tender. Cut off the root end and the leaves and peel the outer layer of skin away, then cut either downwards or across the bulb, then boil in salted water for about 15 minutes, or until tender. For those who like raw fennel, try mixing thin slices into a green salad or shredding it with citrus fruit. Fennel is excellent for making soup or it can be poached, steamed or briefly boiled.
