Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the main body of the dish, providing the base flavour and juicy texture.
- Butter
- Adds fat and richness, rounding out the tomatoes' sharp flavour.
- Baking soda
- Neutralises some of the tomatoes' acidity, mellowing the taste.
- Cream
- Adds fat and softness, giving the stewed tomatoes a smoother, richer texture.
The step that matters
Adding baking soda. Baking soda is a base that reacts with tomato acids and releases gas, so it can foam up. Add only a little, since too much leaves a soapy, bitter taste.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper, cream):
- Potatofits better
- Spinachfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against butter, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
