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 eggs
Break the eggs into a bowl and whisk until frothy.
Add the chopped parsley, mixed herbs, salt, pepper, and optional milk.
Cook the omelet
Melt the butter in a frying pan over medium heat until frothy.
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 the heat and hold the pan in front of the fire until the top shows signs of browning.
Slide the omelet onto a dish and serve immediately, optionally with gravy.

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 when heated, forming the body of the omelet.
- Butter
- Coats the pan to prevent sticking and adds rich flavor and tenderness.
The step that matters
Stirring the egg mixture as it hits the pan. Stirring quickly while the eggs are still liquid keeps curds small and tender, and scraping the bottom prevents sticking and scorching before the omelet 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.
