Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Baked Salmon Trout
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat oven to 300°F (150°C).
Place salmon trout in baking dish and season with coarse sea salt.
Bake and baste
Baste fish often with mixture of butter and water while baking.
Make the sauce
In a saucepan, combine cream and hot water to prevent clotting.
Stir in melted butter, flour, and chopped parsley into cream mixture.
Heat cream mixture in double boiler, adding fish drippings.
Bring to a boil to thicken sauce.
Serve
Once trout is cooked, place on serving dish and pour sauce around it.
Garnish with sprigs of parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon trout
- Is the main protein, cooked gently in the oven until flaky.
- Butter
- Adds richness and helps baste the fish, keeping its surface moist as it bakes.
- Cream
- Forms the base of the sauce, giving it a smooth, rich body.
- Flour
- Thickens the cream sauce when it is heated and brought to a boil.
- Fish drippings (in the method)
- Add savoury flavour to the sauce from the cooking juices of the trout.
The step that matters
Bring the sauce to a boil. Flour needs to reach a boil in the cream to thicken properly. Heating too gently leaves the sauce thin, while cream left at high heat for too long can scorch or separate.
Swap the parsley
How well each one fits the dish's main ingredients (salmon, butter, cream, flour):
- Capersfits better
- Nutmegfits better
- Jalapenofits better
- Parsleythe original
Fit is the average pairing score against salmon, butter, cream, flour. Candidates are from the same food group and used in at least 100 recipes.
