What to use instead of aniseed
Quick answer
The closest option is Fennel seed, rated good. The best substitution in the anise group and the only one that is genuinely comfortable. Same family, same dominant compound, similar size. Fennel is greener and more grassy and aniseed is sweeter and cleaner, so a biscuit made with fennel is a touch more vegetal — noticeable side by side and not otherwise.
It will not do for: Anise spirits and infusions, where the specific sweetness is the product; A dish that also contains fennel, which would simply become more fennelly.

Fennel seed
Good matchUse: ~1.25× by volume — Slightly more fennel than the aniseed called for, since fennel is the milder of the two.

| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| close | close | partial | n/a |
Works for
- Baking, biscuits and sweet breads
- Charcuterie, sausage and fish dishes
- Syrups and poached fruit
Does not work for
- Anise spirits and infusions, where the specific sweetness is the product
- A dish that also contains fennel, which would simply become more fennelly
In baking, a pinch of cinnamon alongside the fennel closes most of the remaining gap — fennel lands greener and less sweet, and the cinnamon restores the warmth that aniseed was contributing.
Star anise
SituationalUse: ~0.5× by volume — Half, ground, and taste as you go. Star anise is markedly stronger and coarser.
Two unrelated plants dominated by the same compound, so the aroma transfers and little else does. Star anise brings a woody bitterness aniseed has none of, and it is coarse where aniseed is delicate — in a fine crumb the difference is obvious.
| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| partial | close | different | n/a |
Works for
- Braises, syrups and poaching liquids where the star can be removed whole
- Robustly flavoured dishes where the woodiness is not exposed
Does not work for
- Delicate biscuits and fine baking, where the coarseness shows
- Any preparation for a child or infant. The two spices do not share a safety picture, and the star anise profile records why that distinction matters.
Keep the names straight. These are not variants of one spice, and the differences run past flavour.
