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

What each ingredient does

Eggs
Set into the structure of the omelette as they cook, holding it together.
Butter
Adds richness and prevents the eggs from sticking to the pan.
Onion
Adds mild aroma and savory flavor to the eggs.

The step that matters

Stir quickly until lightly set. Stirring the eggs in hot butter keeps curds small and tender. Stopping while the eggs are still slightly glossy lets residual heat finish the set without making them dry or rubbery.

Swap the onion

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

  1. Shallotfits better
  2. Chivefits better
  3. Carrotfits better
  4. Onionthe original

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