Pressure canning green beans

On Saturday evening, October 4, 2014, DD used a pressure canner/cooker to can Italian green beans that we bought that morning at the Toledo farmers market. She used the 'raw pack method.'

If the regulator rocked too vigorously, then that meant too mu, and the stove top heat would be turned down. This di

After the 20 minutes ended, the stove heat was turned off. Then it took 35 more minutes for the metal air vent to depress or fall back down, which meant that the pressure was gone and the canner was safe to open.

Jars removed from canner when safe. Water inside the jars still percolated. While the jars sat on the counter and cooled a little, the lids made the sound of popping downward.
