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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh herrings
- Form the main body of the dish, cooking to a tender, flaky texture under the broiler.
- Butter
- Melts over the hot fish to add richness and moisture.
- Fresh parsley
- Adds fresh, herbal aroma that brightens the rich butter.
- Vinegar or lemon juice
- Adds acidity that cuts the richness of the butter and oily fish.
The step that matters
Broil the herrings until cooked through. Herrings are oily and thin, so they cook quickly and can dry out or char if left too long. Cooking until the flesh is opaque and flakes easily keeps them moist and tender.
Swap the parsley
How well each one fits the dish's main ingredients (butter, pepper, vinegar):
- Tarragonfits about as well
- Parsleythe original
- Thymefits less well
- Dillfits less well
Fit is the average pairing score against butter, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
