12 Steps to Canning Stewed Tomatoes

Step 11, Remove Jars

After you have pressured the jars for the correct time, wait until the button on the top of the canner has fallen down. After that, remove the top pressure holder. Wait until any pressure has dissipated and remove the cover. Remove each jar and set them on a newspaper to cool. We wait until the next day and then check to ascertain that all have sealed successfully. Following these instructions carefully we seldom have any failures to seal. When we do most of the time we discover a chip in the rim of the jar.
