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

What each ingredient does

Tomatoes
Break down into a juicy, flavorful sauce that moistens the omelette.
Onion
Adds aromatic sweetness and savory depth when cooked gently without browning.
Butter
Carries the onion and tomato in fat, adding richness and smooth flavor.

The step that matters

Cook the onion without browning. Browned onion turns bitter and sharp and changes the flavor of the sauce. Cooking it gently over moderate heat softens it and draws out its natural sweetness.

Swap the tomato

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

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

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