Consumption advice
Slice it thinly as a key part of seafood and fish salads with a squeeze of lemon and olive oil; its aromatic compounds stimulate digestive enzymes and calm the stomach.
Best preparation methods
Eat it raw and crunchy to enjoy its cool aniseed flavour, or roast the bulb in quarters with olive oil until soft and caramelised so its flavour turns very gently sweet.
