Canning - Jar half empty!
I'm a newbie to canning. I tried to make one 8 oz. jar of grape jelly just to get an idea of the process (just in case!) Well, I under estimated the amount of grapes I'd need. The jar filled just over half way full. I processed it in a boiling bath for the recommended time, but my question is...
In the future, if this happens with multiple jars and I have only enough to fill the last jar half way, should I bother? Will a half full jar go bad anyway with the all the extra headspace?
Thanks for any tips and help on this.
