Why it works: Pepper and lemon 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 ↓
Salmon Croquettes
Ingredients
Directions
Make the mixture
Drain the liquid from the salmon and mince the fish.
Melt butter and mix it with the minced salmon, adding salt, cayenne pepper, nutmeg, and lemon juice.
If the mixture is too dry, add a little of the reserved liquid.
Stir in the bread crumbs until well combined.
Shape and chill
Form the mixture into rolls and coat them thickly with flour.
Place the rolls in a cold place for 1 hour.
Fry and serve
Fry the croquettes in hot fat until golden brown.
Serve on a hot platter, garnished with fresh parsley or lettuce.

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 of the croquettes and gives them their flavor.
- Egg
- Binds the mixture so the croquettes hold together when shaped and fried.
- Bread crumbs
- Absorb moisture and add body, giving the mixture structure for shaping.
- Butter
- Adds richness and fat, which helps the croquettes brown when fried.
- Flour
- Forms a dry coating that helps the outside brown and crisp in the fat.
- Lemon juice
- Adds acidity that brightens the flavor of the salmon.
The step that matters
Chilling the rolls. Chilling firms the egg and fat in the mixture so the rolls hold their shape when they go into hot fat.
