Why it works: Fish and fennel work together. They rank in the top 17% of all ingredient pairs, and cooks put them together in 50 recipes. Both carry anethole, which smells sweet, anise. The science ↓
Salmon, Pickled
Ingredients
Directions
Prepare the brine
Clean the salmon carefully and cut it into pieces about 8 inches long.
Make a strong brine by boiling 2 quarts of water with 2 pounds of coarse sea salt and ½ cup of vinegar.
Drain the brine and let it cool, then pack the fish tightly in a kit or small tub.
Cover and cure
Fill the kit with equal parts of best vinegar and the cooled brine.
Shake the kit to pack the fish tightly and seal it as close as possible.
Let it sit for 1-2 days, then refill as needed.
Keep the kit in a cool place and close it quickly after each use.
Serve
Serve with a garnish of fresh young fennel.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon (in the method)
- The main ingredient, which the brine and vinegar preserve and flavour as it cures.
- Coarse sea salt
- Draws water out of the fish and seasons it, firming the flesh as it cures.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the fish.
The step that matters
Keep the fish fully submerged and sealed. Fish left exposed to air can spoil or dry out and oxidise. Packing the pieces tightly and filling the kit with brine keeps them covered, while a cool place and quick closing limit contamination and warming.
Swap the fennel
How well each one fits the dish's main ingredients (vinegar, fish):
- Tarragonfits better
- Capersfits better
- Pepperfits about as well
- Fennelthe original
Fit is the average pairing score against vinegar, fish. Candidates are from the same food group and used in at least 100 recipes.
