Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sauce
Melt the butter in a saucepan without browning.
Stir in the flour and cook for a minute.
Gradually add the milk, stirring until thickened.
Season with salt and pepper, then remove from heat.
Assemble and bake
In a baking dish, layer the fish, sauce, and bread crumbs until all ingredients are used.
Bake in a 400°F (200°C) oven until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour while the flour cooks without browning.
- Flour
- Thickens the milk into a smooth white sauce that binds the layers together.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats with the flour.
- Salmon
- Provides the main flavour and body of the dish, layered through the sauce.
- Bread crumbs
- Adds a crisp, browned topping as the dish bakes.
The step that matters
Thickening the sauce. Adding milk too quickly or skipping constant stirring can leave lumps. Stirring as the milk is added lets the starch in the flour swell evenly, giving a smooth sauce that holds the layers together.
