Photo showing some hot plum and strawberry jam being ladled into sterilised glass jam jars / storage jars, with the stainless steel saucepan appearing in the back of the picture. Wax discs will be added to the top of the jam, before the lid is closed with the top clip that functions as a lever arm. The metal clips and rubber rings ensure that the glass storage jars remain airtight until the jam is ready to be eaten in the future - on hot buttered toast, or perhaps as a nice strawberry jam sandwich.
