air bubbles in canned tomatoes: a problem?
I tried canning for the first time. I got confused and forgot one step: pressing out the air pockets. But the boiled quartered tomatoes were very liquid, so there aren't many air pockets, but I do see a few little ones. Apparently the seal is good: concave, and I can lift the jar by the lid.
There is a thin air pocket right under the lid anyway, so will a few extra little air pockets matter?
