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 ↓
Omelettes, and Various Ways of Dressing Eggs
Ingredients
Directions
Prepare
In a bowl, beat the eggs with a pinch of salt until well mixed.
Heat the butter in a non-stick skillet over medium heat until melted.
Cook and serve
Pour the eggs into the skillet and cook gently, stirring occasionally.
When the eggs are mostly set but still slightly runny, add the parsley and any optional ingredients.
Fold the omelette in half and cook for another minute until fully set but not browned.
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 as they heat, forming the body of the omelette.
- Butter
- Coats the pan to prevent sticking and adds richness and flavour to the omelette.
The step that matters
Cooking the eggs gently and removing them while slightly runny. Eggs cooked over high heat or for too long turn tough and rubbery as proteins tighten and squeeze out moisture. Stopping while the centre is still slightly soft lets residual heat finish setting them, keeping the omelette tender.
Swap the chive
The recipe marks chive as optional. How well each one fits the dish's main ingredients (egg, butter, parsley):
- Shallotfits about as well
- Chivethe original
- Leekfits about as well
- Potatofits less well
Fit is the average pairing score against egg, butter, parsley. Candidates are from the same food group and used in at least 100 recipes.
