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 ↓
Salmon Croquettes
Ingredients
Directions
Prepare the salmon
Drain the salmon and pour hot water over it to remove excess oil, then dry on cheesecloth and separate into flakes.
Make the white sauce
In a saucepan, melt the butter, add the flour, and cook for a minute.
Gradually whisk in the milk to make a thick white sauce.
Stir in the lemon juice, salt, and cayenne.
Shape and fry
Combine the salmon flakes with the sauce, shape into croquettes, coat in breadcrumbs, and fry until golden.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main protein and flavor, forming the body of the croquettes.
- Butter
- Enriches the sauce and adds fat for flavor and richness.
- Flour
- Thickens the butter and milk into a stable white sauce that binds the salmon.
- Milk
- Forms the liquid base of the white sauce, giving it a smooth, creamy texture.
- Lemon juice
- Adds acidity that brightens the rich salmon and sauce.
The step that matters
Cooking the white sauce to a thick consistency. Flour must be cooked briefly in the melted butter and milk added gradually, or the sauce turns lumpy or stays thin. A well-thickened sauce binds the salmon so the croquettes hold their shape when fried.

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