Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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 sauce
In a saucepan, melt the butter and flour over medium heat until well combined.
Gradually add the hot milk, stirring continuously until the mixture thickens.
Assemble
Butter the bottom of a quart granite pan lightly.
Layer half of the roll biscuits in the pan, followed by half of the salmon and half of the drawn butter.
Repeat the layers with the remaining biscuits, salmon, and drawn butter.
Top with a layer of breadcrumbs.
Bake and serve
Bake at 400°F (200°C) until brown and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red salmon
- Provides the main protein and flaky texture of the casserole.
- Flour
- Its starch thickens the melted butter and milk into a smooth sauce.
- Butter
- Adds richness and flavour to the sauce and moistens the layers.
- Milk
- Forms the liquid base of the sauce that binds the layers together.
- Roll biscuits
- Soak up the sauce and give the casserole a soft, starchy body.
- Breadcrumbs
- Form a top layer that browns in the oven for a crisp finish.
The step that matters
Adding the hot milk gradually. Pouring the milk in slowly while stirring keeps the flour and butter mixture smooth. Flour starch swells and thickens as it heats with liquid, so lumps form if the milk goes in too fast.
