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

What each ingredient does

Soup meat with bone
Releases juices and flavor into the water as it simmers, forming the base of the broth.
Canned tomatoes
Provide the main tomato flavor, acidity and body to the soup.
Onion
Adds savory aromatic depth to the broth during the long simmer.
Sugar
Balances the tomatoes' acidity with a touch of sweetness.

The step that matters

Skim off the fat. Fat from the simmered meat and bones rises and cools into a layer on the surface. Removing it after cooling makes the soup lighter and cleaner-tasting before reheating.

Swap the onion

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

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

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