I am not a newbie and I have had great success with water bath canning, but it is pressure canning that has been a big disappointment. I cannot seem to adjust my gas burners to the correct BTU in order to get a constant rate of pressure. If I turn or look away the pressure rises past the required level and the jar lids fail to seal properly. It feels as though I would have to sit there and stare at the pressure gauge and constatly adjust the burner up and down in order to maintain proper pressure. The problem maybe my stove top, but just inquiring if you have any ideas?
