Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the bulk and body of the chutney as they break down during simmering.
- Onions
- Add savoury sweetness and body that thickens as they cook down.
- Brown sugar
- Adds sweetness that balances the vinegar and helps create a thick, preserved texture.
- Malt vinegar
- Provides acidity that preserves the chutney and sharpens its flavour.
- Green chillies
- Add heat and fresh, sharp flavour to the chutney.
- Horseradish
- Contributes a pungent, sharp heat that deepens as the chutney matures.
The step that matters
Simmering gently for a whole day. Too hard a boil can scorch the sugar and burn the chutney, while gentle heat lets the vegetables soften and the liquid reduce evenly into a thick, well-preserved mass.
