Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour apples
- Provide the bulk and tart flavor that forms the chutney's body.
- Vinegar
- Adds acidity that gives the chutney its sharp flavor and helps preserve it.
- Brown sugar
- Adds sweetness and helps balance the sharpness of the vinegar.
- Raisins
- Add concentrated sweetness and chewy texture as they soften during cooking.
- Onions
- Add savory depth and body as they break down during long simmering.
- Mustard seed
- Adds a sharp, pungent flavor that deepens during cooking.
The step that matters
Cook slowly for 1 hour longer. Long, gentle simmering lets the vinegar mellow and the fruit and onion break down into a thick, cohesive chutney. Cooking too hot can scorch the sugar and leave the mixture uneven or burnt on the bottom of the kettle.
Swap the raisin
