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 ↓
Omelette

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set to form the body of the omelette once heated.
- Butter
- Adds richness and helps the omelette brown in the pan.
- Fresh mushrooms
- Add moisture and savory flavor to the filling.
The step that matters
Cooking the egg mixture. Eggs turn tough and rubbery when overcooked, because the proteins tighten and squeeze out water. Cook over moderate heat only until the eggs are just set and lightly browned.
Swap the parsley
How well each one fits the dish's main ingredients (egg, pepper, mushroom, butter):
- Parsleythe original
- Thymefits about as well
- Nutmegfits less well
- Tarragonfits less well
Fit is the average pairing score against egg, pepper, mushroom, butter. Candidates are from the same food group and used in at least 100 recipes.
