Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stewed tomatoes
- Provide the main body, acidity and flavor of the soup.
- Milk
- Adds creaminess and softens the tomato's sharpness.
- Butter
- Adds richness and carries flavor when melted into the pot.
- Crushed crackers
- Thicken the soup slightly as they absorb liquid and soften.
The step that matters
Pour in the boiling milk and mix well. Adding boiling milk to a thickened base can cause it to curdle or separate. Mixing well as it goes in helps keep the soup smooth and evenly combined.
Swap the tomato
How well each one fits the dish's main ingredients (milk, egg, butter, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against milk, egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
