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
Make the base
In a bowl, cream together the flour and butter.
In a double boiler, heat the milk until boiling, then add the flour and butter mixture.
Stir until smooth and thick, then season with salt and pepper and add the flaked fish.
Spread the mixture on a platter and let it cool.
Shape and fry
Shape the cooled mixture into croquettes, roll in flour, dip in beaten egg, and coat with bread crumbs.
Fry the croquettes in hot oil until golden brown.
Serve
Arrange on a hot dish and garnish with parsley and lemon slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Combined with butter and milk, it thickens the binder that holds the fish together.
- Butter
- Adds fat and richness to the white sauce base, softening the texture.
- Milk
- Forms the liquid of the white sauce, which thickens into a creamy binder.
- Cooked fish
- Provides the main filling and flavor of the croquettes.
- Egg
- Acts as a binder and wash that helps the bread crumbs adhere.
- Bread crumbs
- Form a crisp, golden outer crust when fried.
The step that matters
Cool the mixture fully before shaping. A warm, loose mixture cannot hold its shape and may fall apart. Cooling lets the starch-thickened binder set firm enough to roll and coat without breaking.
Swap the parsley
How well each one fits the dish's main ingredients (flour, butter, milk, pepper, fish, egg, bread):
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
- Cinnamonfits about as well
Fit is the average pairing score against flour, butter, milk, pepper, fish, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
