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 one can of salmon and pour over hot water to remove as much oil as possible.
Dry on a piece of cheese cloth and separate into flakes.
The salmon should yield one and three-fourths cupfuls.
Make the mixture
Add one cupful of thick white sauce, three tablespoonfuls of butter, one-third cupful of flour, and one cupful of milk.
Season with one and one-half teaspoonfuls of lemon juice, three-fourths teaspoonful of salt, and a few grains of cayenne.
Shape and fry
Shape, crumb, and fry the mixture as with other croquettes.

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 (in the method)
- Provides the main flaked body and savory flavor of the croquettes.
- Thick white sauce
- Binds the flakes together and adds creamy moisture.
- Butter
- Adds richness and fat for flavor and a tender texture.
- Flour
- Thickens the sauce so the mixture holds together.
- Milk
- Adds moisture and creaminess to the mixture.
- Lemon juice
- Adds acidity that brightens the flavor of the salmon.
The step that matters
Shape, crumb, and fry the mixture. The white sauce's starch thickens and sets as it cools, binding the flakes so croquettes hold their shape. A firm, well-coated crumb crisps in hot fat, so a loose mixture can break apart during frying.
Swap the lemon
How well each one fits the dish's main ingredients (sauce, butter, flour, cheese, milk):

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