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

What each ingredient does

Milk
Forms the creamy base of the sauce, adding body and richness when thickened with roux.
Butter
Carries the flour into a roux and adds fat for a smooth, rich mouthfeel.
Flour
Thickens the sauce as a roux with the melted butter, giving it structure.
Tomato juice
Provides the acidic, tomato flavour and liquid that makes up the soup's body.
Baking soda
Neutralises some of the tomato juice's acidity, which helps keep the milk from curdling.

The step that matters

Combine the tomato mixture with the cream sauce. Tomato juice is acidic and can curdle milk-based sauces when they meet. Heating the tomato mixture first and letting the baking soda reduce its acidity helps the soup stay smooth.

Swap the tomato

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

  1. Potatofits better
  2. Capsicumfits better
  3. Chivefits better
  4. Tomatothe original

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