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
- Eggs
- Set into soft curds that form the main body of the dish.
- Butter
- Adds fat and richness and keeps the eggs from sticking to the pan.
- Minced tongue, chicken, or ham
- Adds savory meat flavour and substance on top of the toast.
The step that matters
Cook for about 3 minutes, stirring and tossing. Eggs continue to set after leaving the heat, and constant gentle stirring keeps curds small and tender. Overcooking squeezes out moisture and leaves them dry and rubbery.
Swap the parsley
How well each one fits the dish's main ingredients (butter, egg, pepper, chicken):
- Parsleythe original
- Tarragonfits about as well
- Thymefits less well
- Nutmegfits less well
Fit is the average pairing score against butter, egg, pepper, chicken. Candidates are from the same food group and used in at least 100 recipes.
