If you plan to store the chutney in jars, you need to sterilize them first either by putting them in the dishwasher, or in the oven 350°F/180°C/Gas 4 for 20 minutes. Wait until the jars are cooled before putting chutney in.
Finally, if placing in jars, cut out some wax discs and place a disc over the top of the chutney before the lid goes on. This will prevent any excess air touching the chutney and encouraging bacteria.
