Quick Answers

 

 

I just received a call from a lady who had just started pressure canning her turnip greens when she experienced a power outage. She said it had just reached correct pressure, when the lights went out. When the power comes back on, would you recommend that she start timing the canning process from the beginning?


Yes, if the power outage is short, she should start over from the beginning with the timing. If the power is out for more than two hours, she probably should not try to can the product. It could be stored in the refrigerator for several days, but there are too many variables associated with the process to assure that she could produce a safe canned product.
