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
Break the eggs into a bowl and season with salt, pepper, parsley, and chives.
Beat together for about one minute.
Cook and serve
Melt the butter in an omelette pan over medium heat until it smokes.
Pour the eggs into the pan and do not touch them for a few seconds until the bottom starts to set.
Tilt the pan slightly and lift the edge of the omelette with a knife to allow uncooked liquid to flow underneath.
Repeat until no liquid remains and the top is just set.
Insert a knife under the omelette, fold it over, and slide it onto a hot dish.
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 delicate structure that forms the body of the omelette.
- Butter
- Adds richness and prevents the eggs from sticking to the pan.
- Parsley
- Adds fresh, herbal aroma and flavour to the eggs.
- Chives
- Adds mild onion-like aroma and fresh flavour to the eggs.
The step that matters
Keeping the heat moderate while the eggs set. Eggs proteins set quickly at high heat, which toughens and browns the omelette. Gentle heat, with liquid moved to the edges, keeps the texture soft and tender.
Swap the chive
