Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide bulk and pectin, which helps the chutney thicken as it cooks.
- Brown sugar
- Adds sweetness and helps the chutney turn dark and glossy as it reduces.
- Onions
- Add savoury body and soften into the mixture during the long simmer.
- Vinegar
- Provides acidity that preserves the chutney and balances the sweetness.
- Sultanas
- Add chewy texture and concentrated sweetness as they plump in the cooking liquid.
The step that matters
Simmer the mixture for 4 hours, stirring occasionally. A long, gentle simmer evaporates excess liquid so the chutney thickens. Stirring prevents the sugars and fruit from scorching on the base of the pot.
