Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,122 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ingredients
Directions
Prepare the fish
Clean and prepare the fish, cutting it into slices about ½ inch thick.
Cook
Envelop each slice in buttered paper and place on a spit before a good fire.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooking into flaky, moist portions inside the wrapping.
- Butter
- Adds richness and moisture, helping the fish stay tender as it cooks.
- White wine
- Adds acidity and aroma to the seasonings and gravy.
The step that matters
Remove the paper 5 minutes before done. Wrapping in buttered paper keeps the fish moist, but leaving it wrapped too long can leave it steamed and pale. Unwrapping near the end lets the surface brown slightly and lets the cook judge doneness by eye and texture.

Fit is the average pairing score against fish, butter, pepper, parsley, white wine, vinegar. 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).
