I've always wanted to do this but never have as it all seemed to complicated.
So when PP's say you "just boil your jars"... is it really that simple? Like as in, just stick them in a pot of boiling water? What about the lids as well? Do you need special jars? Where do you buy them from? Do you reuse the jars?
I always used to see instructions about boiling them then sticking them in the oven at x temp for y hours etc, do you not need to do this?
Have you ever opened a jar and it's failed and the food is off/mouldy?
