Already set up stock? Pickling and canning as an old skool canadian sport ( ) isn't really about setting up stock...per say... It is about taking produce during the period of harvest ...and preserving it ..for those days when it isn't readily available ..out of season.... Hence the term "preserves" ... fruit, vegetables, pickled and preserved...jams and jellies ...etc... Do that every year ..it is very cost effective...very efficient...and much more healthy than canned goods bought. And so one fills up their cold cellar... Food properly preserved not only lasts for many many many years.... but the freshness of the preserved food is excellent. So it is a process... a lifestyle really... sure it's great to have a huge garden with lots of crops....at harvest.... But what to do with it all when it is all gathered? Eat it all before it spoils? Wasteful and doubtful ... Better to eat some of it ...and preserve most of it. it's about how one spends their time as much as anything...I suppose...
