Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body, moisture and tomato flavour of the stew.
- Onions
- Add savoury sweetness and aroma as they soften in the liquid.
- Bread
- Thickens the stewed liquid and gives the dish body as it breaks down.
- Butter
- Adds richness and a rounded, fatty mouthfeel to the stew.
- Sugar
- Balances the acidity of the tomatoes and adds gentle sweetness.
The step that matters
Add the bread and cook for an additional 30 minutes. Bread absorbs liquid and thickens the stew, so adding it too early or cooking it too briefly can leave the dish thin or pasty. Stirring as it cooks helps it blend evenly into the tomatoes.
Swap the onion
How well each one fits the dish's main ingredients (tomato, butter, sugar, pepper, bread):
