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
- Butter
- Enriches the sauce base and carries the flour, giving it richness.
- Flour
- Thickens the milk into a smooth white sauce that holds the haddock together.
- Milk
- Forms the liquid of the sauce, giving it a creamy, pourable body once thickened.
- Cooked haddock
- Provides the smoky, savoury flavour and the main texture of the topping.
The step that matters
Bringing the flour and milk to a boil. Flour must be cooked in the hot butter and milk must be stirred constantly as it heats. If the sauce is not brought to a boil and held briefly, the starch will not fully swell, leaving a floury taste and a thin, lumpy sauce.
Swap the parsley
How well each one fits the dish's main ingredients (haddock, butter, flour, milk, anchovy, pepper, bread):
- Capersfits about as well
- Parsleythe original
- Nutmegfits about as well
- Thymefits less well
Fit is the average pairing score against haddock, butter, flour, milk, anchovy, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
