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 ↓
Plain Omelette
Ingredients
Directions
Prepare
Crack the eggs into a bowl and beat them lightly.
Heat the butter in a frying pan over medium heat until melted.
Cook and serve
Pour the eggs into the pan and let them cook for a minute.
Firmly hold the handle and jerk the pan toward you to form the omelette into a roll.
Allow it to brown well, then slide it onto a platter.
Garnish with parsley and serve.

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 when cooked, forming the body of the omelette.
- Butter
- Coats the pan so the eggs release cleanly and gains a light golden browning.
The step that matters
Forming the roll with the pan jerk. Eggs set quickly once in the hot pan. Lifting and jerking the pan while the surface is still slightly loose lets the omelette fold over on itself. Waiting too long leaves it stuck and torn, and a cold pan makes it stick.
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.
