The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Eggs
Set and bind the filling into a soft, sliceable mass when heated.
Tomatoes
Provide moisture, acidity, and bulk, softening into a sauce as they simmer.
Butter
Adds richness and fat, carrying flavor and helping the tomatoes soften.

The step that matters

Stirring the eggs over low heat until well set. Egg proteins set at moderate temperatures and can turn rubbery or curdle if overheated. Low heat and steady stirring keep the mixture smooth and tender.

Swap the tomato

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

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

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