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 ↓
Omelet
Ingredients
Directions
Prepare the egg mixture
In a bowl, beat the eggs until frothy.
Add salt, pepper, chopped parsley, and mixed herbs.
Cook the omelet
Melt butter in a frying pan over medium heat.
Pour in the egg mixture and stir quickly, scraping the bottom to prevent sticking.
When the mixture begins to set, push it to one side of the pan to form a semicircle.
Reduce heat and hold the pan in front of the fire to lighten the omelet.
When the top shows signs of browning, slide the omelet onto a dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a structure that holds the omelet together when cooked.
- Butter
- Coats the pan to prevent sticking and adds richness and flavor.
The step that matters
Stirring the egg mixture as it hits the pan. Constant stirring keeps the eggs moving so small curds form evenly and the bottom does not stick or scorch before the top sets.
Swap the parsley
How well each one fits the dish's main ingredients (egg, pepper, butter, milk):
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits about as well
- Tarragonfits less well
Fit is the average pairing score against egg, pepper, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
