Why it works: Parsley and pepper 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 Rissoles
Ingredients
Directions
Prepare the filling
Remove skin and bones from the fish and chop it finely.
In a saucepan, make a smooth thick sauce with flour, butter, and milk.
Flavor the sauce with anchovy, parsley, pepper, and salt; stir in the chopped fish and mix well.
Transfer the mixture to a plate and let it cool.
Shape and fry
Form the mixture into small balls, coat them with egg and bread crumbs.
Fry the balls in hot fat until golden brown; drain on kitchen paper.
Arrange on a dish and garnish with parsley.

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 rissoles and gives them their flavor.
- Flour
- Thickens the milk and butter into a smooth sauce that binds the fish.
- Butter
- Adds richness and helps make the sauce smooth.
- Milk
- Liquid that turns the flour and butter into a thick sauce.
- Bread crumbs
- Form a crisp, golden coating that browns when fried.
The step that matters
Cool the mixture before shaping. A thick sauce that is still warm is too soft to hold its shape, so the balls can fall apart. Cooling lets the starch set so the balls keep their form in the hot fat.
Swap the parsley
How well each one fits the dish's main ingredients (fish, butter, milk, flour, anchovy, pepper, bread):
- Capersfits about as well
- Parsleythe original
- Nutmegfits about as well
- Thymefits less well
Fit is the average pairing score against fish, butter, milk, flour, anchovy, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
