  • Water Bath Method of preserving - advice on jars

    Hi

    Is it safe to use the recycled jam and food jars with their metal lids for the water bath method of preserving? and if so how tight should the lids be during processing.

    This isn't for edibles by the way.. I'm thinking of preserving soap nut liquid (for laundry) this way.

    Thanks

    That should be OK but for edible food you MUST use the proper jars, Le Parfait or Kilner with the correct rubber seals.

      Why is this? (I'm not questioning you, I have yet to try the water bath method and just trying to understand how it works).

        I water bath passata and tomato sauces every year in ordinary jars, I just use the ones with 'pop-up' lids so I can be sure there's a good vacuum seal.

        Generations of Italians have made passata/sauces without the preserving jars you mention, so it's something I will carry on doing

        I wouldn't use ordinary jars for preserving meat recipes though.

          There are different qualities of glass jam jars. Some thicker than others.
          I used Bon Maman type for small quantities and Le Parfait /kilner type jars for larger amounts.

          The thickness of the glass will make a difference- and the quality of the fit of the lid.
          I'm speaking from experience as I've had a frew failures with other , lower quality jars in the past

          Thelm- what make of jam jar do you use??

            I also water bath passata in normal jars (and parfait type, too) so long as the lid fits really well.

              I wonder if maybe I overfilled my jars and that's why they cracked in the water?...may have not been the glass quality then????

                    Bad luck!
                    I've recently noticed some jar sellers are advertising 'new lightweight' glass jars as if it's a plus point Doh.

                      Earlier I was looking at these on ebay and my teenage son came in and asked why I'm looking at lids. I explained that I need new lids for jams etc and he's said, "why don't you just buy lots of smartprice lemon curd from asda for 22p, which is cheaper than the lids, and I can eat it all!"

                          I did a similar thing, I make 'traffic light chilli jelly' i.e red,orange and green jelly and stack the jars on top of each other. I needed lots of the small condiment type jars think mint sauce size, so bought loads from sainsburys chucked them all in one big jar - hey presto loads cheap jars at the fraction of the cost!

                            Great idea mrswadders. I like to do a few of the little jars to give away to elderly relatives and friends that like to have a little bit of what I'm making but wouldn't want a big jar.

                              I just use Kilner type jars from IKEA. I just rinse the jars out with hot water before using and fill it to the top with marmalade, leaving about half a centimetre gap from the top which the lid neatly fills. Then when cool in the refridgerator. I have never any surplus to store. The use of a hot water bath or preferably an autoclave seems to me to be a bit excessive. Anyway that's my two pennyworth.
