Why it works: Cream and butter 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 fish
Preheat the oven to 300°F (150°C).
Bake the salmon trout slowly, basting often with butter and water.
Make the sauce
In a saucepan, combine the cream and hot water to prevent clotting.
Stir in the melted butter, flour, and chopped parsley.
Heat the mixture in a double boiler until thickened.
Serve
Once the trout is cooked, place it on a hot 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
- Provides the main flesh, which stays moist when cooked slowly and basted.
- Cream
- Adds fat and richness, giving the sauce a smooth, silky body.
- Butter
- Adds richness and flavor, and keeps the fish moist when basting.
- Flour
- Thickens the sauce as its starch swells when heated.
- Parsley
- Adds a fresh, herbal aroma and flavor to the sauce.
The step that matters
Heating the cream sauce in the double boiler. Cream can curdle or clot when exposed to direct, strong heat. Gentle indirect heat from a double boiler lets the flour thicken the sauce smoothly without separating it.
Swap the parsley

- Parsleythe original
Fit is the average pairing score against salmon, cream, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
