Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes (in the method)
- Provide the main body, colour and tomato flavour of the soup.
- Flour
- Thickens the white sauce and the browned roux, giving the soup body.
- Butter
- Adds richness and carries flavour while forming the base of the roux.
- Milk
- Forms the creamy base of the white sauce and gives the soup its smooth body.
- Sugar
- Balances the acidity of the tomatoes and adds mild sweetness.
- Beef stock
- Adds savoury depth to the browned roux base.
The step that matters
Adding the milk to the hot tomato mixture. Tomato acid can curdle milk proteins when they meet at high heat. Bringing the mixture to a boil after adding milk, or combining just before serving, can cause separation, so keep the heat gentle and the soup smooth.
