Why it works: Butter and parsley are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 28,563 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Fried Eggs
Ingredients
Directions
Fry the eggs
Heat enough fat in a frying pan to nearly cover the eggs.
Break the eggs into a cup and gently slip them into the hot fat.
Do not turn the eggs; instead, dip the hot fat over them.
Variation and sauce
For a variation, beat the eggs and strain them through a coarse colander into the hot fat, then drain and serve on toast or with bacon.
To make Beurre Noir, add more fat to the frying pan, let it brown, then stir in an equal amount of vinegar and chopped parsley, and pour over the eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main body of the dish; their proteins set when heated, forming the cooked white and yolk.
- Butter or oil
- Conducts heat to the eggs and gives the frying fat flavor and a crisp-edged finish.
- Vinegar
- Adds sharp acidity to the browned butter sauce, balancing its richness.
The step that matters
Do not turn the eggs; spoon hot fat over them. Turning breaks the yolk and sets the eggs unevenly. Spooning hot fat over the top cooks the whites through gently while keeping the yolk intact.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, vinegar):
- Tarragonfits better
- Parsleythe original
- Capersfits about as well
- Dillfits about as well
Fit is the average pairing score against egg, butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
