Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Fresh eggs
Whites set around the yolk to form the cupped egg's firm, tender body.
Butter
Adds richness and a smooth fat layer that carries flavour across the top of the egg.
Minced parsley
Adds a fresh, herbal aroma and a light green note that contrasts with the rich egg.

The step that matters

Cook until the whites are turned and set. Egg whites set between about 60 and 70 degrees C, while yolks thicken at higher temperatures. Gentle steam heat over boiling water sets the white evenly without overcooking the yolk. Lifting the cups too early leaves the white runny; cooking too long makes the yolk chalky and rubbery.

Swap the parsley

How well each one fits the dish's main ingredients (egg, butter):

  1. Nutmegfits about as well
  2. Parsleythe original
  3. Capersfits about as well
  4. Tarragonfits less well

Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
