Why it works: Parsley and pepper 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 ↓
Savoury Omelette
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the eggs
Separate the yolks from the whites of the eggs.
Beat the yolks with the grated onion, salt, pepper, milk, and parsley.
Whisk the egg whites to a stiff froth.
Gently fold the egg whites into the yolk mixture.
Cook and serve
Heat a clean frying pan with the butter until hot.
Pour the egg mixture into the pan.
Stir gently with a wooden spoon until it begins to set.
Allow the bottom to brown slightly.
Transfer the pan to a 350°F (175°C) oven until fully set.
Brown the top in front of the fire.
Carefully turn it out onto a hot dish and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped by whisking give the omelette its light, airy structure, while yolks enrich it and help it set.
- Milk
- Adds moisture so the omelette stays tender rather than dry and rubbery.
- Butter
- Fat for the pan that keeps the eggs from sticking and promotes gentle browning on the base.
The step that matters
Folding the whites into the yolk mixture. Whites hold air only when whisked to a stiff froth. Folding gently preserves that air, so the omelette rises and stays light instead of deflating into a dense, flat layer.
Swap the onion
How well each one fits the dish's main ingredients (egg, milk, parsley, pepper, butter):

- Onionthe original
Fit is the average pairing score against egg, milk, parsley, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
