How to sterilise your jars
Heat the oven to 160C/140C fan/gas 3. Meanwhile, wash your jars in hot soapy water, rinse well and stand upside down, still wet, on a baking tray. Put in the oven for 10-15 mins, then fill while still warm.
Heat the oil in a preserving pan or large wide saucepan. Add the onions and fry for a few mins until starting to soften. Add the ginger and cook until soft, another 1-2 mins.
Stir in the spices for 1-2 mins to release their aroma, then add the peppers, vinegar and sugar. Simmer for 10 mins until the sugar has dissolved and the peppers are starting to soften.
Stir in the sultanas and peaches, and simmer for another 45 mins until the chutney is pulpy rather than watery. Leave to stand for 15 mins; then, while still warm, pot into sterilised jars. Will keep for 3 months stored in a cool, dark place. Transfer to the fridge once opened and eat within a month.
