Why it works: Butter and parsley are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 28,563 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
How to Make an Omelette
Ingredients
Directions
Prepare
Heat a frying pan over medium heat and add the butter.
Break the eggs into a bowl, add parsley and salt, and beat gently until just combined.
Cook and serve
Pour the egg mixture into the pan once the butter is melted.
As it cooks, lift the edges with a knife and push towards the center.
When the omelette is set, fold it 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 omelette.
- Butter
- Adds richness and helps prevent the eggs from sticking to the pan.
- Parsley
- Adds fresh, herbal aroma and a little colour to the eggs.
The step that matters
Lift the edges and push the egg towards the center as it cooks. Moving the cooking egg lets liquid egg flow onto the hot pan surface, producing small, even curds and a tender set. Leaving it still makes the bottom overcook and toughen before the top sets.
Swap the parsley
How well each one fits the dish's main ingredients (butter, egg):
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
- Tarragonfits less well
Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
