In her book, 'Green Cuisine, The Organic Vegetable
Cookbook', Anna Ross says, "Fennel has a distinct taste of
aniseed, which you either love or hate. This flavour goes very
well with fish, so you could serve Fennel & Potato Gratin as
an accompaniment. I also like to serve it as a main vegetarian
course with Roasted Carrots with Thyme. When you use fennel raw
in salads, remove the first layer of skin if it is tough. Use the
feathery leaves in salads or as a garnish." She also provides
recipes for Fennel Soup, Fennel Couscous and Kohlrabi &
Fennel Soup. For the latter, slice and sauté the two
vegetables plus an onion, add stock and seasoning and simmer
until tender. Finally liquidise with a little milk until smooth
and reheat before serving. The green-white 'bulbs' can also be
cooked whole in boiling water, or steamed, and served with a
white or cheese sauce.
