I just made my first batch ever of Chilli Jam. I made use of powdered pectin as suggested, and it seems to be setting well! How are these jellies to be sealed? Can they be put in a water bath, and if so, for how long? Or should the jars just be kept in the fridge? Please advise. Mine is going to be hot! Hot chillies, I guess! Thank you!
Nigella's Chilli Jam (from Christmas and on the Nigella website) is sealed into sterilized jars. There are a couple of ways to sterilize jars and Nigella considers a jar that has been washed on a hot cycle in the dishwasher and comes fresh from the machine (without so much as a finger touching the inside) is sterilized.
Otherwise you can wash the jars and lids in hot soapy water, rinse with clean hot water and dry them in a cool (140c/285F) oven. Use jars with plastic coated metal lids as the acid in the jam could react with the metal. Once sealed with the lids the jam should keep in a cool dry place for up to 1 year, though once it is opened it should be kept in the fridge and consumed within 1 month.
