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

What each ingredient does

Eggs
Whisked whites lighten the mixture and yolks give richness and set structure to the omelette.
Butter
Very hot butter cooks the eggs quickly and adds fat and flavour to the surface.
Thick cream
Adds moisture and richness, keeping the omelette tender rather than dry.

The step that matters

Cook the omelette quickly over very hot butter. Egg proteins set quickly at high heat. If the pan is not hot enough or the cooking is slow, the omelette becomes dense and dry. Rolling it as soon as it sets keeps it tender and prevents overcooking.

Swap the parsley

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

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

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