OK, went looking for a relevant thread and couldn't spot one and I need some help.

I had my first attempt at the weekend at a chilli tomato chutney and it turned out well. Except we bought some jars and we followed what we thought was the process for sealing them but they don't appear to be air tight.

Can anyone provide me advice on:

- Where to buy decent jars for long term storage of chutney/preserves

- The process you've used for sealing said jars.

Any tips are appreciated.
