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

What each ingredient does

Tomato pulp
Provides the main body, flavor and acidity of the soup.
Baking soda
Neutralizes some of the tomato's acidity, reducing sharpness and helping prevent curdling.
Milk
Makes the soup creamy and mellow, forming the base that the tomato is added to.
Butter
Adds richness and a smooth, silky mouthfeel.
Granulated sugar
Rounds out tomato acidity with a touch of sweetness.

The step that matters

Adding the tomato mixture to the milk mixture. Acidic tomato can curdle hot milk. Baking soda lowers acidity, but the tomato should be added to the milk gradually and kept from overboiling so the soup stays smooth rather than separating.

Swap the tomato

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

  1. Capsicumfits better
  2. Potatofits better
  3. Sweet potatofits better
  4. Tomatothe original

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