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 and release their own juices as they stew.
- Crackers or toasted bread
- Absorb the tomato liquid and thicken the stew as it cooks.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the tomatoes.
- Onion
- Contributes savoury aroma that deepens during the long, gentle cooking.
- Sugar
- Adds sweetness that softens the natural acidity of the tomatoes.
The step that matters
Add the crackers or toasted bread and stew for one hour. Starches in the crackers or bread absorb liquid and thicken the stew, but they can scorch or stick if heat is too high. Stewing gently in a double boiler spreads heat evenly and prevents this.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, butter, sugar, bread):
- Capsicumfits better
- Potatofits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, butter, sugar, bread. Candidates are from the same food group and used in at least 100 recipes.
