Looking for canning jars that I can freeze in
I want to cook soups and freeze them in canning jars and have ordered a product online that will vacuum seal these jars for me. I have never canned but I found online that there are canning jars that I can freeze in.
I know that I must leave space in the jar for expansion. Do I wait until the soup is cooled off before putting it into the jars?
Must I purchase these jars online only? Would the canning jars that they sell at Ace, etc. not be advisable for freezing?
