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 ↓
Frejh Salmon
Ingredients
Directions
Prepare the salmon
Cut fresh salmon into fillets and wipe them clean and dry.
Melt butter in a pan, add a little flour and coarse sea salt.
Add the salmon fillets to the pan and coat them in the butter mixture.
Make the anchovy sauce
Wash and bone the anchovies, then cut them into small pieces.
Cut the leek into three or four long pieces and set in a saucepan with butter and flour.
Add the anchovies, leek, capers, pepper, salt, nutmeg, warm water, and vinegar to the saucepan.
Shake the saucepan until it boils.
Simmer until ready.
Cook and serve
Place the salmon on a clean grill and broil over a low fire.
Turn the salmon to cook evenly until done.
Remove the leek from the sauce, pour the sauce into a dish, and place the broiled salmon on top.
Garnish with quartered lemons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh salmon fillets
- Forms the main protein, cooking to a flaky texture under low, even heat.
- Butter
- Coats the salmon and enriches the sauce, adding fat for moisture and flavour.
- Flour
- Thickens the butter and sauce, giving them body.
- Anchovies
- Melt into the sauce, adding a deep, savoury saltiness.
- Vinegar
- Adds acidity that brightens and balances the rich butter sauce.
- Capers
- Add a briny, sharp note that cuts through the richness of the sauce.
The step that matters
Turn the salmon to cook evenly until done. Salmon cooks quickly and dries out when overcooked, and under broiling heat the surface can char before the centre sets. Turning helps even cooking, so check doneness often.
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.
