Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Supply the main body and liquid that forms the stewed sauce as they soften.
- Onions
- Add savory sweetness and body as they soften into the stew.
- Bread
- Thickens the stewed liquid and gives the dish a soft, body-rich texture.
- Butter
- Adds richness and a smooth mouthfeel to the stewed sauce.
- Sugar
- Balances the acidity of the tomatoes and adds mild sweetness.
The step that matters
Add the bread. Bread thickens the liquid as it absorbs juices and softens. Adding it too early over long cooking can break it down into a paste, so it is added late in the simmer.
Swap the onion
How well each one fits the dish's main ingredients (tomato, butter, sugar, pepper, bread):
- Capsicumfits better
- Potatofits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against tomato, butter, sugar, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
