My mom loved using paraffin - last summer when she stayed with me she got upset that I used lids on my jelly.My grandmother only did HWB, but she never canned meat. She did jelly, tomatoes, ...... all beans were frozen....
I remember the cupboard where all the jars were stored.... but now i am blanking as to what was in them!!!
I would help her with the jelly and the tomatoes... oh, and the pickles! Lots of pickles! Still kills me that her pickling recipe is gone for forever!
Pickles and tomatoes was just HWB, but for jelly, we first covered the jelly with a paraffin seal, then put them in the HWB. And we always reused the paraffin.
Yeah, all those acidic foods just need boiled, not pressurized. Kind of nice.
We never had grocery store produce all the time I was a kid. Dad's garden/orchard provided all we needed. And we ate certain things only seasonally, like lettuce, because they couldn't be stored, frozen, or canned. I think this stemmed from living so far from a store for lots of years and then continued even though we moved into a town because it was 'what we did'.
