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

What each ingredient does

Tomatoes
Provide the main body, moisture and bright acidity that form the topping.
Onions
Add savory sweetness and aroma as they soften during cooking.
Milk or cream
Adds richness and a smoother, creamier texture to the cooked vegetables.
Butter
Adds fat for richness and a silky mouthfeel in the finished topping.
Toasted bread
Gives a firm base that soaks up the topping while keeping some crispness.

The step that matters

Drain the water. Excess liquid from the cooked tomatoes and onions would thin the mixture and make the toast soggy, so draining it first keeps the topping thick enough to hold on the bread.

Swap the onion

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

  1. Capsicumfits better
  2. Potatofits better
  3. Asparagusfits better
  4. Onionthe original

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