A. Both Dill and fennel are weeds and belong to the family of aromatic plants. However, they are not the same. Dill is used mainly for its dried seed in pickling or fresh in sauces and salad dressings. It blends the distinctive flavour of its seed with pleasant green. On the other hand, the fennel is more anise or liquorice-like. The farmer directs the plant's energy into the bulb when not grown for its seed. Fennel bulb is a versatile, mild veggie that is superb, sautéed, or grilled in Mediterranean dishes or raw in salads.
