Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned tomatoes
- Form the acidic, flavourful base of the soup and give it its body.
- Milk
- Adds creaminess and softens the sharp tomato flavour.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Baking soda
- Neutralises some of the tomato acid, which helps keep the milk from curdling.
- Sugar
- Balances the acidity of the tomatoes with a touch of sweetness.
- Light bread
- Toasted squares add crunch that contrasts with the smooth soup.
The step that matters
Add the milk. Tomatoes are acidic, and acid can make milk curdle when the two are heated together. The tomatoes are taken off the heat before the milk goes in, and baking soda reduces the acidity, which helps keep the soup smooth.
Swap the clove
How well each one fits the dish's main ingredients (tomato, milk, butter, sugar, celery, bread):
- Cinnamonfits better
- Thymefits better
- Nutmegfits better
- Clovethe original
Fit is the average pairing score against tomato, milk, butter, sugar, celery, bread. Candidates are from the same food group and used in at least 100 recipes.
