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 ↓
Steamed Fish
Ingredients
Directions
Prepare
Place the fish on a plate, with the tail in its mouth.
Pour the vinegar over the fish and season with pepper and salt.
Let the fish chill on ice or in a very cold place for 1 hour.
Steam and serve
Pour off the vinegar and steam the fish for 20 to 30 minutes, or until fully cooked.
Drain the fish well and serve on a napkin with curled parsley.
Serve drawn butter in a sauce boat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole fish
- Forms the main body of the dish and is cooked through by steaming.
- Vinegar
- Acidity that is poured off before steaming, leaving a sharp flavour on the flesh during chilling.
The step that matters
Chill the fish before steaming. The fish needs its full hour in cold conditions so the flesh firms and the vinegar seasons it evenly. Pouring off the vinegar before steaming keeps the cooked fish from tasting overly sour.
Swap the parsley
How well each one fits the dish's main ingredients (fish, vinegar, pepper, butter):
- Tarragonfits about as well
- Parsleythe original
- Thymefits less well
- Capersfits less well
Fit is the average pairing score against fish, vinegar, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
