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):
- Capsicumfits better
- Potatofits better
- Shallotfits about as well
- 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.
