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 moist, tangy sauce that adds acidity and body.
Onion
Softens and turns sweet and mellow in the butter, adding aroma to the sauce.
Butter
Adds fat and rich flavor and helps the onion cook gently without sticking.

The step that matters

Cook the onion without allowing it to color. Browning onion creates bitter, sharp flavors and a darker color. Cooking it gently in butter until soft keeps the sauce mild, sweet and pale.

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.
