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 and tomato flavour of the soup.
Cornstarch
Thickens the soup as it boils, giving it a smooth, creamy body.
Butter
Adds richness and helps the cornstarch blend smoothly into the hot tomato mixture.
Milk
Makes the soup creamy and mellows the tomato's acidity.

The step that matters

Stirring cornstarch into the boiling tomato mixture. Cornstarch clumps if added without being mixed with fat first or if it is dumped in. Mixing it with the fat and stirring it in while the mixture boils lets the starch disperse and thicken evenly into a smooth soup.

Flavor stand-ins for the clove

How well each one fits the dish's main ingredients (tomato, onion, garlic, sugar, butter, milk):

  1. Cinnamonbetter flavor fit
  2. Thymebetter flavor fit
  3. Cuminbetter flavor fit
  4. Clovethe original

Fit is the average pairing score against tomato, onion, garlic, sugar, butter, milk. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
