Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide tartness and body as the chutney breaks down over the long steeping.
- Brown sugar
- Adds sweetness and a molasses-like depth that balances the sharp vinegar.
- Vinegar
- Acts as the main preservative and gives the chutney its sharp acidity.
- Raisins
- Add sweetness and chewy texture as they soften in the mixture.
- Red chillis
- Supply heat and pungency to the chutney.
The step that matters
Keeping the mixture warm for a month. The jar must stay at a steady warm temperature and be stirred regularly so the fruit breaks down evenly. Too little heat slows the process, and uneven heat or neglect can let spoilage start before the vinegar has fully preserved the mixture.
Swap the tomato
How well each one fits the dish's main ingredients (apple, sugar, raisin, vinegar, lemon):
- Arrowrootfits better
- Shallotfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against apple, sugar, raisin, vinegar, lemon. Candidates are from the same food group and used in at least 100 recipes.
