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 ↓
Fish Croquettes
Ingredients
Directions
Make the croquette mixture
In a saucepan, melt the butter and mix in the flour and cream over medium heat.
Remove from heat and stir in the egg yolk and seasoning.
Add the cold dressed fish and mix until smooth.
Let the mixture cool.
Shape and fry
Form the mixture into balls, then coat them in egg and bread crumbs.
Fry the croquettes in hot fat until golden brown.
Make the gravy and serve
For the gravy, boil the fish bones, fins, and tails with the onion.
Add the anchovy and season to taste before serving with the croquettes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold dressed fish
- Forms the main body of the croquettes, giving them their filling texture.
- Butter
- Enriches the base and adds richness and flavour to the mixture.
- Flour
- Thickens the butter and cream into a binding base that holds the mixture together.
- Cream
- Adds moisture and softness, helping the mixture stay tender.
- Egg yolk
- Binds the mixture and helps it set firm when cooked.
- Bread crumbs
- Form a crisp outer coating that browns during frying.
The step that matters
Let the mixture cool before shaping. A warm, soft mixture is too loose to form into balls and may fall apart or split in the hot fat. Cooling lets the starch and egg firm up so the croquettes hold their shape during frying.
Swap the onion
How well each one fits the dish's main ingredients (flour, butter, cream, egg, fish, bread, anchovy):
- Asparagusfits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against flour, butter, cream, egg, fish, bread, anchovy. Candidates are from the same food group and used in at least 100 recipes.
