Why it works: Salmon and fennel work together. They rank in the top 16% of all ingredient pairs, and cooks put them together in 253 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
To Pickle Salmon
Ingredients
Directions
Cook the fish
Split the salmon down the back and cut it into pieces.
Place the pieces on a fish strainer and boil in salted water until tender.
Pack the pieces tightly in a pan and boil the remaining fish in the same water.
Pickle and preserve
Add 2 ¼ cups of vinegar and a handful of fennel to the water, then boil for 5 minutes.
Strain the liquid over the fish and let it cool completely.
Once cold, add 1 tablespoon of salad oil and keep the fish covered to preserve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main flesh, which firms and flakes as it cooks in the poaching water.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the fish.
- Fennel
- Adds a light anise-like aroma to the pickling liquid.
- Salad oil
- Adds fat that coats the fish and softens its texture.
The step that matters
Let the fish cool completely before adding the oil. Adding oil to warm fish can make it greasy and uneven, and the fish needs to be fully cold before it is covered so that moisture does not collect and soften it.
