Why it works: Parsley and chive match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 2,150 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
The Omelette
Ingredients
Directions
In a clean, dry shallow pan, heat enough butter to moisten the surface.
When the butter stops sizzling and turns brown, pour in the egg mixture.
Lift the set edges of the omelette to allow the uncooked mixture to flow underneath.
Continue this until the omelette is mostly set, then give it a final shake.
Turn the omelette onto a hot dish before it fully sets.
Optionally, add melted butter, chopped parsley, and chives to the dish.

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 omelette.
- Butter
- Moistens the pan and adds richness and a light browned flavour.
The step that matters
Lifting the set edges while the mixture is still runny. Lifting lets uncooked egg flow underneath to cook evenly. Leaving the eggs still for too long over-sets and toughens them, while stopping too early leaves the centre wet.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (egg, butter, chive):
- Capersfits better
- Tarragonfits about as well
- Parsleythe original
- Nutmegfits less well
Fit is the average pairing score against egg, butter, chive. Candidates are from the same food group and used in at least 100 recipes.
