Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Omelette Savoury
Ingredients
Directions
Prepare
Tap the center of the eggs sharply and separate the whites into a dry dinner plate, placing the yolks in a basin.
Beat the yolks and mix in pepper, salt, parsley, ham, onion, and mixed herbs.
Beat the egg whites with a fork until stiff enough to turn the plate upside down without them falling.
Gently fold the beaten whites into the yolk mixture.
Cook and serve
Heat a small piece of butter in an omelette pan, then pour it off and add a fresh piece of butter.
Warm the butter in the pan, pour in the mixture, and cook until browned on one side.
Fold the omelette and transfer it to a hot dish.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift and structure, while yolks set to give the omelette its body.
- Butter
- Adds fat for richness and helps the omelette brown and release from the pan.
- Ham
- Adds savory flavor and chewy texture to the filling.
- Onion
- Adds aromatic sweetness and savory depth to the filling.
The step that matters
Folding the beaten whites into the yolks. Whites hold air only when beaten to stiff peaks; folding gently keeps that air in, so the omelette stays light instead of deflating into a dense, flat layer.
Swap the onion
How well each one fits the dish's main ingredients (egg, pepper, parsley, ham, butter):
- Shallotfits better
- Carrotfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against egg, pepper, parsley, ham, butter. Candidates are from the same food group and used in at least 100 recipes.
