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 ↓
A Plain Omelette
Ingredients
Directions
Prepare
Break the eggs into a bowl and add milk, parsley, pepper, and salt.
Beat the mixture gently for a few seconds.
Heat a clean omelette pan and wipe it with paper.
Cook the omelette
Add butter to the pan and let it froth without browning.

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 they cook, forming the body of the omelette.
- Milk or cream
- Adds moisture and softness, keeping the cooked eggs tender rather than dry.
- Butter or salad oil
- Coats the pan to prevent sticking and adds richness and flavour.
The step that matters
Cook over medium heat, scraping the bottom until it begins to set. Heat that is too high sets and browns the bottom before the top sets, leaving a tough, overcooked omelette. Gentle heat and scraping keep the curds small and the texture soft.
Swap the parsley
How well each one fits the dish's main ingredients (egg, milk, pepper, butter):
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits about as well
- Tarragonfits less well
Fit is the average pairing score against egg, milk, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
