Fennel seed

FEN-uhl

Foeniculum vulgare

Also called saunf.

Sweet, warm, gentle licorice.

Fennel seed is the dried fruit of Foeniculum vulgare, a feathery Mediterranean plant in the carrot family, with a sweet, gentle licorice flavor milder than anise. The greenish-tan seeds are warm and aromatic and turn nutty when toasted. Fennel is a signature of Italian sausage and many fish dishes, and across South Asia the seeds are chewed plain as a breath freshener. It belongs equally in savory cooking and baking. Whole seeds keep far better than ground and are easy to crush by hand.

Common in Italian, Indian, Middle Eastern cooking.

Whole vs ground

How to handle it

Toast whole seeds to bring out a nutty side, then crush into sausage mixes, rubs, and tomato sauces. They are also chewed plain after meals.

Storage

Airtight and dark. Whole seeds hold a year or more; ground fades within months.

Buying note

Choose plump, green-tinged seeds with a strong sweet smell. Dull gray seeds are old.
