If you’re making your own preserves, make sure your glass jars are scrupulously clean so that the contents won’t perish. Our steps show the jars being used to keep homemade mincemeat, but you will find this technique useful when making any marmalade, jam or chutney.

Sterilising jars

Step 1:

Heat oven to 140C/120C fan/gas 1. Wash the jars in hot, soapy water, then rinse well. Place the jars on a baking sheet and put them in the oven to dry completely. If using Kilner jars, boil the rubber seals, as dry heat damages them.
