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 ↓
Stewed Skate
Ingredients
Directions
Prepare the fish
Skin the skate and cut it into square pieces.
Brown the skate pieces in butter in a frying pan.
Make the sauce
In a pot, boil the skin and parings in 3 pints of water with an onion, pepper, and salt.
Strain the broth and thicken it with a little butter mixed with flour.
Add finely chopped parsley, chives, hot vinegar, mushroom catsup, Harvey sauce, and a little cayenne.
Boil the sauce and add the skate 5 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Skate
- Forms the main body of the dish and provides the fish that cooks gently in the sauce.
- Flour
- Thickens the broth with butter so the sauce becomes smooth and cohesive.
- Butter
- Adds richness and browns the skate pieces in the frying pan.
- Hot vinegar
- Adds sharpness that brightens the sauce and balances its richness.
The step that matters
Add the skate 5 minutes before serving. Fish is delicate and overcooks quickly; adding it to a boiling sauce only shortly before serving keeps the flesh tender and moist rather than dry and flaky.
Swap the onion
How well each one fits the dish's main ingredients (butter, pepper, flour, parsley, chive, vinegar, mushroom):
- Shallotfits better
- Spinachfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against butter, pepper, flour, parsley, chive, vinegar, mushroom. Candidates are from the same food group and used in at least 100 recipes.
