Fennel vs anise
Both are small seeds from the carrot family, and both taste of licorice, which is why recipes and even shops sometimes confuse them. The difference is mostly one of strength and sweetness.
Fennel seed
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.
Anise
Sweet, strong licorice, warm
Anise is the small seed of Pimpinella anisum, a Mediterranean plant in the carrot family, with a sweet, warm, strongly licorice flavor from anethole. It is the original licorice spice and flavors liqueurs like ouzo, sambuca, and pastis, as well as breads, cookies, and some sausages. Despite the shared name and flavor, it is unrelated to star anise, a different plant that happens to make the same compound. Anise is milder and sweeter than fennel in some uses and stronger in others, so the three licorice spices are easy to mix up.
Which to use when
Use fennel when you want a gentle, grassy licorice that stays in the background, in sausage, roast pork, and tomato sauces. Use anise when you want the licorice itself to be the flavor, in cookies, breads, and licorice sweets. Fennel is milder and a little greener; anise is sweeter and more concentrated. They swap in a pinch, with fennel used a touch more heavily.
