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 ↓
Fish Croquettes
Ingredients
Directions
Prepare the filling
Remove all skin and bones from the cold fish and mash it until smooth.
Add butter, pepper, coarse sea salt, ground mace, and optional crab or lobster sauce.
Form the mixture into egg-sized portions.
Add bread crumbs if the mixture is too soft.
Coat and fry
Dip each portion into a beaten egg, then coat with fine bread crumbs.
Fry in boiling lard until golden brown, then drain.
Serve
Serve on a napkin garnished with fried parsley or with tartare sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fish
- Forms the main body of the croquettes, providing the flavour and bulk of the filling.
- Butter
- Adds fat and richness, keeping the mashed filling tender and moist.
- Bread crumbs
- Absorb moisture to firm a soft mixture and form a crisp golden coating when fried.
- Egg
- Binds the coating so the crumbs stick, and helps it set and brown in the hot lard.
The step that matters
Fry in boiling lard until golden brown. The fat must be hot enough to brown the crumb coating quickly; if it is too cool, the croquettes absorb grease, turn soggy and may fall apart before the coating sets.
Swap the mace
How well each one fits the dish's main ingredients (fish, butter, pepper, crab, bread, egg, parsley):
- Capersfits better
- Tarragonfits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against fish, butter, pepper, crab, bread, egg, parsley. Candidates are from the same food group and used in at least 100 recipes.
