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
- Fresh salmon
- Forms the main body of the dish and carries the flavor of the sauce.
- Butter
- Adds richness and fat that helps coat the salmon and carry flavor.
- Flour
- Thickens the butter and the sauce, giving them body and a smoother texture.
- Anchovies
- Provide a deep, savory saltiness that melts into the sauce.
- Capers
- Add a sharp, briny acidity that cuts through the rich butter.
- Vinegar
- Adds acidity that brightens the sauce and balances its richness.
The step that matters
Simmer the sauce until ready. Flour thickens only when the mixture is heated and simmered long enough, so undercooking leaves the sauce thin and pasty-tasting. Boiling hard or too long can scorch the butter and break the sauce.
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.
