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 the vegetables together.
Potatoes
Add body and starch so the omelette feels substantial and holds its shape.
Onion
Adds savory sweetness and aroma as it softens in the eggs.
Green pepper
Contributes fresh, slightly bitter flavor and a bit of crisp texture.
Butter
Adds richness and helps keep the omelette from sticking to the pan.

The step that matters

Pour the eggs into the hot butter and wait for them to thicken before adding vegetables. Eggs cooked in very hot fat set quickly at the edges and stay tender in the middle. Adding vegetables only after the eggs begin to thicken keeps them from sinking and breaking the set base, so the omelette holds together when turned.

Swap the clove

The recipe marks clove as optional. How well each one fits the dish's main ingredients (egg, onion, pepper, potato, parsley, garlic, butter):

  1. Thymefits better
  2. Dillfits better
  3. Marjoramfits better
  4. Clovethe original

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