Pressure Canning and leaking
I canned some crushed tomatoes and in a few cases some of the liquid
bubbled out during the canning procedure. Still safe to keep it? (other than having to wipe down the cooled bottles) |

Do this above a padded surface in case the lid comes off. If you can lift the jar by the lid and it stays intact, you should be fine. How full did you pack the jars? Instructions say to leave 1/2" headspace but that doesn't seem like much to me. I think some folks here leave an inch - that's more space for bubbling inside the jar. Also, are you following instructions carefully for letting pressure drop on its own off the heat and then letting the jars sit in the hot water for 10 minutes after you've removed the canner lid? I'll be watching to see what others say. -- -Barb, Mother Superior, HOSSSPoJ For your listening pleasu http://www.am1500.com/pcast/80509.mp3 -- from the MN State Fair, 8-29-07 |

I left an inch or more in order to try to avoid the bubble over but I
think because the crushed tomatoes were so thick bubbles formed trapped amongst the tomatoes and that led to the leaking. Well the seals are good so it looks like I am ok. Yes, I let the jars cool down slowly (75 minutes) in the canner before taking the lid off. When I open up and look in I can see the water is discoloured from overflow.

During the pressure canner cooldown, the inside of the canner is positive with respect to atmospheric and so the inside remains sterile. During this time the food temp starts dropping and as soon as that happens, the inside of the jar pressure starts to drop and pulls the jar lid into a seal. As long as all jars have sealed themselves before the pressure canner reaches atmospheric pressure, it's impossible for germs to get inside the canner and thus inside the jars. This is why it's important to let the canner cool down by itself and not pull the pressure release as soon as processing is over, or pull the lid off or some such. Ted |
