Yesterday I canned again the ground beef from the non-sealed quart jars (that I processed the previous day), this time using pints. Again, it was hard to keep the temperature even at 11PSI, on occasions it went up to 13PSI. And the result was that many of the jar lids got burned, and they did not seal.
I think I've been lucky so far with good seals, now the limitations of the glass top stove are becoming apparent. I'm gonna check out those portable electric stoves.
I'm wondering if you're not using enough water or whether using more water would alleviate this problem. I haven't had this happen yet and the stove I've been canning on is completely inconsistent so I usually end up canning between 13-15PSI because I can't regulate it to a consistent temperature (so annoying). It is an old electric stove, so maybe it being on glass really is the problem.
Is there water in the pressure canner when you open it after a canning session?
Maybe this is the answer for anyone who's on a burner that doesn't provide consistent heat - crank it up so that it's at 13-15 PSI instead of 11. That way, even if the temperature is inconsistent, at least it's staying above the standard minimum.
Just an idea...
