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 ↓

Ingredients
Directions
Prepare the eggs
Beat the eggs well for about 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a structure that gives the omelette its body when cooked.
- Butter
- Adds richness and flavour and helps keep the eggs from sticking to the pan.
- Chives
- Add a mild onion-like aroma and fresh flavour.
- Parsley
- Adds fresh, green flavour and aroma.
The step that matters
Stir until slightly brown. Eggs set quickly under high heat and turn tough and rubbery if overcooked. Stop stirring when the surface is just set and lightly coloured, since residual heat finishes the cooking and keeps the omelette tender.
Swap the chive
How well each one fits the dish's main ingredients (egg, pepper, parsley, butter):
- Shallotfits about as well
- Chivethe original
- Carrotfits about as well
- Capsicumfits about as well
Fit is the average pairing score against egg, pepper, parsley, butter. Candidates are from the same food group and used in at least 100 recipes.
