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 ↓
Croquettes of Fish
Ingredients
Directions
Make the fish mixture
Remove the skin and bones from the cold fish and break it into small pieces.
In a saucepan, melt the butter over medium heat until light brown.
Stir in the flour and cook for a minute, then gradually add the hot milk while stirring until thickened.
Mix in the anchovy sauce, nutmeg, cayenne, and season with salt and pepper.
Add the fish to the sauce and gently heat until nearly boiling, then transfer to a plate and let cool until firm.
Shape and fry
Shape the cooled mixture into cork-like forms, then dip each in beaten egg and roll in bread crumbs.
Fry the croquettes in hot lard at 385°F (196°C) until golden brown.
Serve with fried parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fish
- Provides the main body and flavor of the croquettes.
- Butter
- Enriches the sauce and adds richness and flavor to the base.
- Flour
- Thickens the milk into a sauce that holds the fish together.
- Hot milk
- Forms the liquid base of the sauce, giving it a smooth, creamy texture.
- Egg
- Binds the coating so bread crumbs adhere and form a crisp shell.
The step that matters
Let the mixture cool until firm. The sauce must set fully before shaping; if it is still warm and soft, the croquettes will lose their shape and may break apart or split in the hot lard.
