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 a soft, creamy custard as they cook and thicken.
- Milk
- Dilutes the eggs so they set gently and stay moist and tender.
- Butter
- Adds richness and a smooth, silky mouthfeel to the eggs.
- Spaghetti
- Adds bulk and chewy texture to the soft eggs.
- Button mushrooms
- Add earthy flavour and a moist, meaty bite.
The step that matters
Cook until the mixture thickens. Eggs set from heat and can turn grainy or curdle if overcooked. Cooking gently over hot water and stopping once thickened keeps the texture soft and creamy.
Swap the parsley
How well each one fits the dish's main ingredients (butter, milk, egg, mushroom, pepper):
- Parsleythe original
- Nutmegfits about as well
- Thymefits about as well
- Cinnamonfits less well
Fit is the average pairing score against butter, milk, egg, mushroom, pepper. Candidates are from the same food group and used in at least 100 recipes.
