Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,118 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
The recipe
Ingredients
Contains: milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Parboil the small onions until tender.
In a stewpan, combine red wine, butter, onions, parsley, chives, bay leaf, cloves, salt, pepper, fine spicery, and sweet basil.
Add the prepared fish and bring to a quick boil over high heat.
Thicken the sauce with butter mixed with flour, adding anchovy butter as well.
Carefully shake the pan to avoid breaking the fish and ensure even thickening.
Dish the fish and sauce, and if the sauce is too thin, reduce it further.

Fit is the average pairing score against onion, red wine, fish, butter, parsley, chive, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
