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 filling together.
Butter
Adds richness and carries heat for frying the tomatoes, helping them brown lightly.
Tomatoes
Add moisture, acidity and a fresh flavour to the filling once cooked down.

The step that matters

Stew the tomatoes. If the tomatoes stay watery, they release liquid into the omelette and make it soggy or hard to fold. Cooking them down until most of the moisture has evaporated keeps the filling thick and the omelette intact.

Swap the tomato

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

  1. Capsicumfits better
  2. Asparagusfits better
  3. Chivefits better
  4. Tomatothe original

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