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 as they cook, forming the body of the omelette.
Milk or cream
Adds moisture and softness, keeping the cooked eggs tender rather than dry.
Butter or salad oil
Coats the pan to prevent sticking and adds richness and flavour.

The step that matters

Cook over medium heat, scraping the bottom until it begins to set. Heat that is too high sets and browns the bottom before the top sets, leaving a tough, overcooked omelette. Gentle heat and scraping keep the curds small and the texture soft.

Swap the parsley

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

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

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