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 ↓
French Omelet
Ingredients
Directions
Prepare the eggs
Break the eggs into a bowl and season with salt.
Beat the eggs with an egg beater for 4 minutes.
Cook and serve
Melt the butter in a skillet over medium heat.
Pour the eggs into the skillet and draw from the edge to the center with a fork.
When the omelet begins to firm, let it cook for 30 seconds without stirring.
Fold the omelet over from each side to meet in the center.
Turn the omelet onto a hot dish with the folded side underneath 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, custard-like structure when heated, forming the body of the omelet.
- Butter
- Adds richness and keeps the eggs from sticking to the skillet while they cook.
The step that matters
Drawing the eggs from edge to center. Moving the eggs as they start to set forms small, tender curds. If the eggs are left still too long, the surface overcooks and turns tough and rubbery instead of soft and creamy.
Swap the parsley
The recipe marks parsley as optional. 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.
