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 ↓
Omelette
Ingredients
Directions
Prepare
Beat the eggs in a bowl and season with salt and pepper.
Heat a pan and add butter until melted.
Cook and serve
Pour the egg mixture into the pan and cook until the edges are set.
Gently lift the edges with a spatula to allow uncooked egg to flow underneath.
When the omelette is golden brown and the inside is soft, fold it in half.
Transfer to a hot dish and serve immediately, optionally garnished with parsley or cheese.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set by heat to form the omelette's structure and body.
- Butter
- Adds fat for richness and helps prevent the egg from sticking to the pan.
The step that matters
Lifting the edges while the egg cooks. Egg proteins set as they heat. Lifting the edges lets liquid egg flow underneath to cook, keeping the omelette tender rather than rubbery and overcooked.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (egg, pepper, butter, cheese, ham, oyster):
- Parsleythe original
- Thymefits about as well
- Nutmegfits less well
- Capersfits less well
Fit is the average pairing score against egg, pepper, butter, cheese, ham, oyster. Candidates are from the same food group and used in at least 100 recipes.
