Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fish Croquettes
Ingredients
Directions
Make the white sauce
Make a white sauce by melting butter, adding flour, and gradually whisking in milk.
Season the sauce with lemon juice, salt, and pepper.
Shape and coat
Combine the cold flaked fish with the white sauce.
Shape the mixture into croquettes.
Roll each croquette in egg, then in bread crumbs, and again in egg.
Fry
Fry in hot lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold flaked fish
- Forms the main body and flavour of the croquettes.
- Butter
- Enriches the white sauce and adds richness to the mixture.
- Flour
- Thickens the milk into a white sauce that binds the fish.
- Milk
- Forms the liquid base of the white sauce, giving it a smooth, creamy body.
- Egg
- Coats the croquettes so the breadcrumbs stick and help them hold together when fried.
- Bread crumbs
- Forms a crisp, golden outer crust when fried.
The step that matters
Chilling the mixture before shaping. The white sauce must be thick and cold enough to hold its shape. If the mixture is too warm or loose, the croquettes can slump or burst open in the hot lard, so the fish and sauce need to be firm enough to handle.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
