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 ↓

Add flour and a pinch of salt.
Gradually add milk until the mixture thickens.
Boil for a couple of minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main body and flavor of the croquettes.
- Breadcrumbs
- Absorb moisture and bind the salmon into a shapeable mixture.
- Butter
- Adds richness and fat to the sauce base.
- Flour
- Thickens the butter and milk into a smooth sauce that holds the mixture together.
- Milk
- Forms the liquid base of the sauce that thickens with the flour.
The step that matters
Boiling the thickened sauce. The sauce must be cooked long enough for the starch in the flour to swell and fully thicken. Undercooked flour leaves a raw, pasty taste and a loose mixture that won't hold its shape when fried.
