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 acidity of the soup.
Chopped onion
Adds savory aroma that builds the base flavor.
Cloves
Add a warm, spiced aroma to the soup.

The step that matters

Cook the tomatoes until soft. Tomatoes that are fully softened break down easily, so the mixture strains smoothly and the flavors from the onion and cloves are released into the liquid. Undercooked tomatoes leave a firm, grainy texture and a sharper, less developed taste.

Swap the onion

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

  1. Capsicumfits better
  2. Carrotfits better
  3. Eggplantfits better
  4. Onionthe original

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