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 ↓
Salmon Croquettes
Ingredients
Directions
Prepare
Drain the salmon and remove bones and skin.
In a saucepan, melt the butter, then whisk in the flour and cook until smooth.
Gradually add the milk, cooking until the sauce thickens.
Season the sauce with salt, pepper, and lemon juice.
Let the mixture cool, then stir in the salmon.
Shape and coat
Shape the mixture into croquettes.
Dip each croquette in beaten egg, then coat with bread crumbs.
Fry
Fry the croquettes in deep fat until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main body and flavor of the croquettes.
- Butter
- Adds richness and flavor to the starting roux.
- Flour
- Thickens the milk with the butter to form a binding white sauce.
- Milk
- Liquid that turns the roux into a thick sauce that holds the mixture together.
- Egg
- Coats the croquettes so the bread crumbs adhere and help them set when fried.
- Bread crumbs
- Form a crisp, golden outer coating during frying.
The step that matters
Cool the sauce before adding the salmon. A warm, thin sauce will not hold its shape, so the croquettes may slump or split when shaped and fried. Letting the mixture cool and thicken makes it firm enough to form and coat.
