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 ↓
Omelettes, and Various Ways of Dressing Eggs
Ingredients
Directions
Prepare
In a bowl, beat the eggs with a pinch of salt until well combined.
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, until the eggs are just set but still moist.
Sprinkle the chopped herbs over the omelette before folding it in half.
Serve immediately, ensuring the omelette is not overcooked.

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 cook, forming the body of the omelette.
- Butter
- Coats the pan so the eggs release cleanly and add richness and flavour.
- Fresh herbs
- Add aroma and a fresh, green flavour to the eggs.
The step that matters
Cook gently until just set but still moist. Egg proteins tighten as they heat, and past that point they squeeze out water and turn dry and rubbery. Removing the omelette while it is still moist keeps it tender, and it keeps cooking briefly off the heat.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter):
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
- Tarragonfits less well
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
