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
Ingredients
Directions
Prepare the fish
Clean the fish and cut it into pieces.
In a stewpan, add enough white broth to cover the fish.
Boil down 2-3 dabs or flounders with their fins and trimmings to make broth.
Make the broth
Add parsley, pepper, chopped onion, horseradish, and bay leaf to the broth.
Bring the broth to a boil.
Skim the broth carefully.
Cook and serve
Cook the fish until it is done, about a few minutes.
Thicken the sauce with flour and butter.
Add white wine, lemon juice, essence of anchovy, and catsup to the sauce.
Strain the gravy over the fish.
Serve the fish in a deep dish lined with toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as it cooks, giving it body.
- Butter
- Enriches the sauce and adds richness to the thickened gravy.
- White wine
- Adds acidity and aroma to the sauce.
- Lemon juice
- Adds brightness and acidity that balances the rich sauce.
- Whitings, flounders, dabs, gudgeons, or eels
- Forms the main body of the dish, cooked through in the broth.
The step that matters
Skim the broth carefully. Skimming removes foam and impurities that would cloud the broth and give the sauce a muddy flavour. Clear broth gives a cleaner-tasting gravy.
Swap the horseradish
How well each one fits the dish's main ingredients (whiting, veal, parsley, pepper, onion, flour, butter):
- Shallotfits better
- Carrotfits better
- Chivefits better
- Horseradishthe original
Fit is the average pairing score against whiting, veal, parsley, pepper, onion, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
