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 ↓
Omelet, Savoury
Ingredients
Directions
Prepare the eggs
Beat and strain the eggs.
Add parsley, onion, pepper, and salt; beat again.
Cook and serve
Melt butter in a small round frying pan over moderate heat.
Pour in the egg mixture and stir until the omelet is set.
Turn onto a hot dish, fold in half, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a tender structure as they cook, forming the body of the omelet.
- Butter
- Adds richness and helps keep the omelet from sticking to the pan.
- Parsley
- Contributes fresh, herbal aroma and a little color.
The step that matters
Stirring until the omelet is set. Eggs turn from liquid to firm as their proteins coagulate with heat. Stop cooking once the surface is just set, since overcooked eggs become dry, tough and rubbery.
Swap the onion
How well each one fits the dish's main ingredients (egg, parsley, pepper, butter):
- Shallotfits better
- Chivefits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against egg, parsley, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
