Fennel seed is the oval, green or yellowish brown dried fruit of the fennel bush, which is of Mediterranean origin and belongs to the Umbelliferae family. It grows to be several feet tall with umbels of small, yellow flowers that look very similar to a dill plant. Fennel has a sweet and aromatic taste, similar to anise and licorice. They contain essential oils and other ingredients which have a strong seasoning action. The leaves and stalks of fennel can be eaten as a vegetable. Fennel seed is used for meats and poultry, but even more for fish and seafood. It is also used to flavor baked goods and liquors. Another important use for fennel is in Italian sausage.
