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
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Open the tin of salmon, drain the liquid, and place the fish in a bowl.
Add the bread crumbs, pepper, salt, lemon juice, chopped cucumber, and beaten egg to the bowl and mix the ingredients thoroughly.
Form the mixture into small flat rounds.
Bake and serve
Place the rounds on a well-buttered baking bag, ensuring they are spaced apart, then secure the bag and keep it flat.
Slide the bag into a 400°F (200°C) oven.
Use a large fish slice to help put in and take out the cooked croquettes.

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 supplies the savoury flavour.
- Bread crumbs
- Absorb moisture and help the mixture hold its shape while cooking.
- Egg
- Binds the mixture together so the rounds hold their form.
The step that matters
Forming and spacing the rounds. The mixture is soft and binds only as it sets. Flat, evenly sized rounds cook at the same rate, and spacing them on the bag lets heat reach each one so they do not stick together or stay raw in the middle.
Swap the cucumber
The recipe marks cucumber as optional. How well each one fits the dish's main ingredients (salmon, bread, pepper, lemon, egg, butter):
- Asparagusfits better
- Chivefits about as well
- Capsicumfits about as well
- Cucumberthe original
Fit is the average pairing score against salmon, bread, pepper, lemon, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
