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

What each ingredient does

Canned tomatoes
Provide the main body, acidity and flavour of the soup.
Milk
Forms the creamy base of the soup and adds richness and mild sweetness.
Flour
Thickens the milk into a smooth, body-rich base when cooked.
Baking soda
Neutralises some tomato acidity, reducing sharpness and helping keep the milk from curdling.
Butter
Adds fat for a smoother mouthfeel and rounder flavour.

The step that matters

Combine the tomatoes and milk. Tomato acid can curdle hot milk. Adding the baking soda to the tomatoes first and combining them carefully helps keep the soup smooth rather than grainy.

Swap the tomato

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

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

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