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 ↓

Ingredients
Directions
Prepare
Clean and bone the haddock, then cut it into fillets.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock fillets
- Provides the main protein, which firms and turns opaque as it cooks.
- Flour
- Coats the fish so it browns in the butter and thickens the pan gravy.
- Butter
- Conducts heat for sautéing and adds richness and browning flavour.
The step that matters
Sautéing the floured fillets. Flour browns quickly, so the butter should be hot but not smoking. Too little heat leaves the coating pale and soggy; too much burns it before the fish cooks through.
Swap the parsley
How well each one fits the dish's main ingredients (haddock, pepper, flour, butter):
- Parsleythe original
- Capersfits about as well
- Turmericfits about as well
- Nutmegfits less well
Fit is the average pairing score against haddock, pepper, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
