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 ↓
Truffle Omelet
Ingredients
Directions
Prepare the truffles
Wash the truffles and place them in a saucepan with enough white wine to cover them.
Boil for 10 minutes with the lid on, then keep warm in the stock for 30 minutes.
Remove the truffles, peel, and chop them finely.
Make and serve the omelet
In a bowl, beat the eggs and mix in chopped parsley, salt, and pepper.
Heat the butter in a frying pan, pour in the egg mixture, and cook until yellow but not brown.
Add the chopped truffles and a bit of the cooking liquid to the center of the omelet, fold it over, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Truffles
- Provide the main aroma and flavor that defines the dish.
- Eggs
- Set into a soft structure that wraps and holds the filling.
- Butter
- Adds richness and gives the omelet a golden surface when cooked.
- White wine
- Gently poaches the truffles and carries their aroma into the cooking liquid.
The step that matters
Cook the omelet until yellow but not brown. High heat or long cooking makes egg proteins tighten and brown, leaving the omelet dry and rubbery. Gentle heat keeps it tender and moist around the truffle filling.
Swap the parsley
How well each one fits the dish's main ingredients (truffle, white wine, egg, pepper, butter):
- Parsleythe original
- Tarragonfits about as well
- Thymefits about as well
- Nutmegfits less well
Fit is the average pairing score against truffle, white wine, egg, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
