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.
Bake the trout
Preheat the oven to 300°F (150°C).
Place the salmon trout in a baking dish and baste it often with melted butter and water.
Make the sauce
In a saucepan, combine the cream with a few spoonfuls of hot water to prevent clotting.
Stir the melted butter, flour, and chopped parsley into the cream mixture.
Heat the cream mixture in a double boiler, adding the gravy from the baking dish.
Bring to a boil to thicken the sauce.
Serve
Once the trout is cooked, place it on a serving dish and pour the 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
- Forms the main body of the dish, cooking through in the oven to become flaky.
- Butter
- Adds richness and flavour, and basting keeps the fish moist as it bakes.
- Cream
- Gives the sauce its rich body and smooth, creamy texture.
- Flour
- Thickens the sauce as its starch swells when heated with the liquids.
The step that matters
Adding hot water to the cream. Cream can curdle or separate when it meets heat too suddenly, so warming it gradually with a little hot water helps keep the sauce smooth.
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.
