Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the minced salmon and crumbs together so the croquettes hold their shape.
- Cracker crumbs
- Absorb moisture and add body to the mixture, and form a crisp outer coating.
- Canned salmon
- Provides the main protein and flavor, forming the body of the croquettes.
The step that matters
Fry in hot lard until golden brown. If the lard is not hot enough, the croquettes absorb excess fat and turn greasy, and the coating browns unevenly. Hot fat sets the crumb coating quickly and gives a crisp, golden surface.
Swap the onion
How well each one fits the dish's main ingredients (salmon, pepper, egg, parsley):
- Chivefits better
- Asparagusfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against salmon, pepper, egg, parsley. Candidates are from the same food group and used in at least 100 recipes.
