Storing Chilli Jam Without Sterilising Jars

Our answer

Nigella's Chilli Jam (from NIGELLA CHRISTMAS) is usually stored in jars that have been sterilised by washing in warm water and then drying in a warm oven. If the jars are not sterilised then the jam can turn mouldy quite quickly as bacteria that is potentially in the jars may grow. If the jars are not sterilised then the Chilli Jam should be stored in the fridge and used within one month.

In addition you must make sure that the jam has cooled to room temperature before transferring it cold, unsterilised jars. If the jam is hot and the jars are cold then there is a risk that when the heat of the jam comes into contact with the cold glass then the glass will crack. If the glass jars crack then the jam must be discarded as there could be small shards of glass in the jam.
