Making Jams & Marmalade

[williaj]

Found a great way to recycle the jars with pop-up tops eg Lloyd Grossmans, etc
if you sterilise them in the dishwasher, or with boiling water, along with the lids.
Then fill the jar up to the top without spilling over and put on the lid. After a while when the jam is cooling you will hear the lids click. This is the lid sealing under the vacuum created. This means there is no fiddling with greaseproof paper, paper lids and elastic bands. The jam will never get mouldy on the top and keeps for ages.

yes it works a treat,I've been doing this for years, at least you are not introducing a waxed disc thats been in the drawer for ages and is definatly not sterile so the jam will keep for years, absolutely no bugs or mould spores can get in,we just finished a jar thats dated 9/8/2008 it was fine.

Surely makers of homemade jam and marmalade have been re-using screwtop jars ever since they were invented. My grandma and my mum always did.

Properly made homemade jam never goes mouldy with or without waxed paper etc etc
