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

What each ingredient does

Milk
Forms the creamy body of the soup and carries the other flavors.
Stewed tomatoes
Provide the main tomato flavor and acidity, with liquid for the soup.
Baking soda
Neutralizes some of the tomato's acidity, which keeps the milk from curdling as easily.
Butter
Adds richness and a smooth mouthfeel to the soup.
Crushed crackers
Thicken the soup as they absorb liquid and soften.

The step that matters

Combine the tomato mixture with the hot milk. Acidic tomatoes can curdle milk when they meet it. Keeping the milk hot, adding the tomato mixture while it is near boiling, and pairing it with baking soda helps keep the soup smooth rather than separated.

Swap the tomato

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

  1. Potatofits better
  2. Capsicumfits better
  3. Tomatothe original
  4. Asparagusfits about as well

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