Since it is that time of year again I thought I pose this question because I don't want the same thing happening again. Firstly, I followed the directions regarding the seals and put them in simmering water, took them off the heat and placed on my jars and secured them with the screw band, and processed. Everything turned out great except (don't laugh) my husband has to drill a hole on the seal to release the pressure so we can get the jars open. My sister-in-law told me you that the new seals do not require heating before using yet all the books I have read says to do so. If this is the case I won't heat them up before using, if not why are they so stuck?
