Should bubbles come out when canning?
“When air bubbles are not removed, the air trapped by the food will essentially add to the headspace. Too much headspace can lead to seal failures.” Opt for wooden or plastic tools (like Ball’s official “bubble freer,” shown here) when shifting the contents to remove headspace.
What happens if I use 15 lbs pressure instead of 10 when canning tomatoes?
pressure is used and zero or one minute processing, there is not sufficient time for all of the air to vent out of the canner and for the internal canner temperature to raise. Using 15 lb. pressure at zero or one minute processing will increase spoilage.”
