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 ↓
Cheese Omelette
Ingredients
Directions
Prepare
Beat the egg yolks and whites separately.
Season with salt and pepper.
Melt the butter in a large frying pan over low heat.
Make the omelette
In a bowl, combine the milk, egg yolks, and 2 whole beaten eggs.
Pour the mixture into the pan and cook slowly, watching carefully.

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 as their proteins coagulate, and the whipped whites add lightness.
- Butter
- Adds richness and flavour, and helps keep the omelette from sticking to the pan.
- Milk
- Adds moisture and keeps the eggs soft and tender as they cook.
- Cheese
- Adds savoury flavour and melts into the omelette, giving it richness.
The step that matters
Cook slowly over low heat. Egg proteins set gently at lower temperatures. Too much heat makes the eggs tough and rubbery, and can scorch the butter before the omelette is ready.
Swap the parsley
How well each one fits the dish's main ingredients (egg, pepper, butter, milk, cheese):
- Nutmegfits about as well
- Parsleythe original
- Thymefits about as well
- Cinnamonfits about as well
Fit is the average pairing score against egg, pepper, butter, milk, cheese. Candidates are from the same food group and used in at least 100 recipes.
