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 ↓
Broiling Fish
Ingredients
Directions
Prepare
Cut slices from fresh salmon and wipe them clean and dry.
Melt butter with a little flour and coarse sea salt, then coat the salmon slices in the butter mixture.
Wash, bone, and chop the anchovies and leek.
Make the sauce
In a saucepan, melt butter, add flour, anchovies, leek, capers, pepper, salt, nutmeg, warm water, and vinegar.
Bring the sauce to a boil, then simmer until ready.
Broil and serve
Place the salmon on a clean grill and broil over a clear, slow 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
- Salmon
- Its flesh cooks to a tender, flaky texture and carries the flavour of the dish.
- Butter
- Adds richness and fat that helps the salmon brown and keeps it moist while broiling.
- Flour
- Thickens the butter and the sauce so they hold together rather than running thin.
- Anchovies
- Add a deep, savoury saltiness that gives the sauce its main character.
- 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
Turn the salmon to cook evenly until done. Salmon cooks quickly and unevenly over direct heat, so turning it helps the thinner parts avoid drying out before the thicker centre is cooked through.
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.
