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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Form the main body of the dish, cooked through under the broiler.
- Melted butter
- Adds moisture and richness, helping the crumbs brown and the fish stay juicy.
- Bread crumbs
- Form a crisp, golden crust over the fish while holding in moisture.
- Fine herbs
- Add aroma and savory flavor to the crumb topping.
The step that matters
Broil the herrings. Fish cooks quickly under intense heat and can dry out or burn before the crumbs brown. Keeping the crumb layers moist with butter helps them brown evenly while the flesh stays tender.
Swap the parsley
How well each one fits the dish's main ingredients (butter, bread, pepper):
- Parsleythe original
- Sagefits about as well
- Thymefits less well
- Nutmegfits less well
Fit is the average pairing score against butter, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
