Is tomato sauce safe if the water evaporated in the canner?
When I opened my canner after the allotted time, I became aware that water had evaporated and the lids were not immersed in the water -as when I started. Most likely evaporation the cans sealed almost immediately. Is my tomatoe sauce safe?
Best Answer
If the water was boiling the whole time, you are fine.
There is research-supported (finally) evidence that "Steam canning" is actually just as effective as boiling water bath canning, if done properly. Unfortunately, the folks that have been insisting that you must have everything submerged are rather slow to change recommendations based on the research, after decades of claiming that they didn't recommend it since there was no research. It makes me wonder what in heck their actual agenda is.
In any case, if your boiling water bath was boiling the whole time, the portion of the jars that was "steam-processed" would have been steam processed properly, so you're good.
Note that while the research was aimed at the "steam canner" pots, a partially full boiling water bath in a normal pot is exactly the same above waterline when the lid is on.

Removing jars from the canner too quickly after processing causes stress that sends liquid out of the jar.Can you boil canning jars too long?
Boiling temperatures kill molds and yeast, along with some forms of bacteria. But it does not kill the bacteria that cause botulism (food poisoning) or their toxins. So you could boil your green beans for three hours in a water bath canner and still have toxic food in your pantry, even though the jars had sealed.Should the water cover the jars when pressure canning?
