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 skin and bones from the fish and chop it coarsely.
Heat the butter in a pan, then add the fish and mashed potatoes.
Season with salt and pepper, and add enough milk to moisten the mixture.
Stir over heat until well mixed, then transfer to a plate and let cool.
Shape and coat
Form the mixture into cork-shaped pieces.
Brush with beaten egg mixed with 1 tablespoon of milk or water, then coat with breadcrumbs.
Fry and serve
Fry in hot oil for about 5 minutes until golden brown.
Drain well and serve garnished with crisply-fried parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked fish
- Provides the main body and flavor of the croquettes.
- Mashed potatoes
- Binds the mixture and keeps the filling soft and moist.
- Butter
- Adds richness and fat that carries flavor into the filling.
- Egg
- Binds the coating so the breadcrumbs adhere and form a crust.
- Breadcrumbs
- Form a crisp, golden outer crust when fried.
The step that matters
Let the mixture cool before shaping. A warm, soft mixture is sticky and hard to form, and it can break apart or lose its shape during coating and frying. Cooling firms the starches and fats so the pieces hold together in hot oil.
Swap the parsley
How well each one fits the dish's main ingredients (fish, potato, butter, egg, milk, pepper):
- Parsleythe original
- Nutmegfits about as well
- Thymefits less well
- Dillfits less well
Fit is the average pairing score against fish, potato, butter, egg, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
