I read here somewhere that vacola jars can be used in a pressure canner, so I assume this is a different animal? If so, what is a pressure canner and does it have advantages over the vacola jars?
I was going to ask if one can preserve pumpkin in vacola jars, but then I read a post here regarding acid content of foods, so can I assume that pumpkin can't be preserved in vacola jars?
Thank you for your time.
Le Loup.
