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

What each ingredient does

Eggs
Set when heated, forming the body of the omelet.
Flour
Thickens the mixture slightly, giving it a smoother, more stable texture.
Tomatoes
Add moisture and a tangy, fresh flavor to the omelet.

The step that matters

Fry the mixture until cooked through. Egg proteins set with heat, so the omelet needs enough heat to firm fully. Undercooked egg stays runny in the center, while overcooking makes it dry and rubbery.

Swap the tomato

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

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

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