Fennel
Fennel is a pale green or white bulbous vegetable with delicate, feathery fronds and a mild anise-like flavor that becomes sweeter when cooked. It belongs to the carrot family and is prized in Mediterranean cuisine for its versatility, as both the bulb and fronds are edible. The bulb provides a crisp, slightly sweet texture when raw and develops a tender, caramelized quality when roasted or braised. Fennel's subtle licorice notes make it a sophisticated ingredient that bridges vegetable and herb applications.
