Why it works: Leek and capers share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 27 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main protein, which sets and firms as it cooks over the fire.
- Butter
- Adds fat and richness, and helps the salmon coating brown and stay moist.
- Flour
- Thickens the butter and the sauce, giving them body and a smooth texture.
- Anchovies
- Contribute deep savory flavour that melts into the sauce as it simmers.
- Capers
- Add a sharp, briny acidity that balances the rich butter and fish.
- Vinegar
- Adds acidity that brightens the sauce and cuts through its richness.
The step that matters
Simmering the sauce after it boils. Once the flour-thickened sauce reaches a boil it must simmer gently; boiling hard can scorch the flour and break the sauce, leaving it lumpy or grainy.
Swap the nutmeg
How well each one fits the dish's main ingredients (salmon, butter, flour, leek, capers, pepper, vinegar):
- Tarragonfits better
- Parsleyfits better
- Thymefits better
- Nutmegthe original
Fit is the average pairing score against salmon, butter, flour, leek, capers, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
