Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Baked Salmon
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 350°F (175°C).
Scale and wash the salmon, leaving the skin on.
Season the fish with coarse sea salt and black pepper.
Place the salmon in a baking pan with a small amount of water and cover tightly.
Bake and serve
Bake for about 30 minutes, then add the butter.
Continue baking for another 15 minutes.
Remove the fish and garnish with parsley.
To make the sauce, combine vinegar and flour in the pan to thicken.
Serve the salmon very hot.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 and is cooked gently until flaky.
- Butter
- Adds fat and richness to the fish as it bakes.
- Vinegar
- Adds acidity that brightens the sauce and balances the richness of the fat.
- Flour
- Thickens the pan liquids into a sauce as it is stirred in with the vinegar.
The step that matters
Covering the salmon tightly with a little water. A tight cover traps steam so the fish cooks gently and stays moist. Too little liquid or a loose cover can let the fish dry out before the centre is cooked through.
Swap the parsley
How well each one fits the dish's main ingredients (salmon, pepper, butter, vinegar, flour):
- Capersfits about as well
- Tarragonfits about as well
- Parsleythe original
- Dillfits about as well
Fit is the average pairing score against salmon, pepper, butter, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
