Why it works: Fennel and pepper match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,216 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Fish, Pickled
Ingredients
Directions
Make the pickle
Mix the water and vinegar in a bowl.
Add the sliced onion, fresh fennel, pepper, and coarse sea salt.
Pickle and store
Place the boiled fish in a deep dish and pour the pickle over it.
Baste the fish frequently to keep it well moistened.
Store in a cool place; it will keep for several days.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the acidity that flavours and firms the fish in the pickle.
- Onion
- Adds aromatic flavour that infuses into the pickling liquid.
- Fennel
- Adds a mild aniseed aroma to the pickle.
The step that matters
Basting the fish frequently. Fish left in an acidic liquid can dry out or become unevenly flavoured at the surface. Regular basting keeps the surface moist and lets the pickle penetrate evenly.
Swap the onion
How well each one fits the dish's main ingredients (fish, vinegar, fennel, pepper):
- Capsicumfits better
- Mustardfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against fish, vinegar, fennel, pepper. Candidates are from the same food group and used in at least 100 recipes.
