Why it works: Capers and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 624 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Salmon, Braised
Ingredients
Directions
Prepare
Wash the salmon in salted water and dry it with a cloth.
Fold the salmon in oiled paper and place it on a drainer over a saucepan of boiling water.
Steam and make the sauce
Steam the salmon for about 45 minutes until cooked through.
Drain the salmon and prepare the sauce by bruising the capers and stirring them into the melted butter.
Add the anchovy, mustard, soy sauce, and cayenne to the butter and simmer gently for 3-4 minutes.
Stir in the sherry and lemon juice, then pour the sauce over the salmon before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main body of the dish, cooking gently to a moist, flaky texture when steamed.
- Capers
- Add sharp, briny acidity that cuts through the richness of the butter.
- Butter
- Provides fat and a rich, smooth body to the sauce.
- Anchovy
- Adds deep savoury flavour that rounds out the sauce.
- Sherry
- Adds acidity and aromatic depth to the sauce.
- Lemon juice
- Brightens the sauce with acidity.
The step that matters
Steaming the salmon until just cooked through. Salmon becomes dry and firm when overcooked, because protein fibres tighten and squeeze out moisture. Steaming gently in oiled paper helps trap moisture, so checking doneness carefully matters.
Swap the mustard
How well each one fits the dish's main ingredients (salmon, capers, butter, anchovy, sauce, pepper, sherry):
- Shallotfits better
- Chivefits about as well
- Mustardthe original
- Horseradishfits about as well
Fit is the average pairing score against salmon, capers, butter, anchovy, sauce, pepper, sherry. Candidates are from the same food group and used in at least 100 recipes.
