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 and liquid that breaks down into the stew as it cooks.
The step that matters
Stew the tomatoes slowly. Slow cooking lets the tomatoes break down and gradually lose water through evaporation, concentrating their flavour. High heat can scorch the bottom of the pan before the tomatoes have thickened.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (tomato, pepper, mace):
- Capsicumfits better
- Carrotfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, mace. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
