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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the base
Melt the butter in a saucepan and add the chopped onion or parsley.
Stir in the flour and cook until thick like cake dough.
Assemble and bake
In a baking dish, layer the dough and salmon alternately.
Cover the top with bread crumbs and moisten with cream or milk.
Cover the dish tightly and bake at 400°F (200°C).
Remove the cover and brown the top slightly before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, carrying flavour through the thick base.
- Flour
- Cooked with butter, it thickens the mixture into a firm, dough-like layer that holds the salmon.
- Salmon
- Provides the main protein and flavour, set in place by the cooked flour base.
- Bread crumbs
- Form a crisp, golden topping that browns when the cover is removed.
- Cream or milk
- Adds moisture to the crumb topping and helps it brown gently in the oven.
The step that matters
Cook the flour into the butter until thick. Cooking the flour in butter until it thickens sets the base into a firm, dough-like layer. If it stays thin, the layers will not hold together and the casserole will be loose when served.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, salmon, bread, cream):
- Leekfits better
- Chivefits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against butter, flour, salmon, bread, cream. Candidates are from the same food group and used in at least 100 recipes.
