Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provides the main body, moisture and tangy flavor of the soup.
- Whipped cream
- Adds fat for richness and a silky, smooth texture.
- Baking soda
- Neutralizes some of the tomatoes' acidity, mellowing their sharpness.
The step that matters
Stir in the whipped cream and serve immediately. Whipped cream is a foam that deflates and can separate when heated or held, so it should be added at the end, off the heat if possible, and served right away.
Swap the tomato
How well each one fits the dish's main ingredients (chicken, pepper, cream):
- Capsicumfits better
- Potatofits better
- Spinachfits better
- Tomatothe original
Fit is the average pairing score against chicken, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
