How long should I wait until I put new jars in? Currently canning some banana peppers. I have a large stock pot set up with a 3 jar canning rack. I just finished a round of jars in the stock pot and the water was boiling. How cool should I let the water get before I put the next round of jars in to start heating up? I don't want to break my jars by putting them into the pot when its too hot.

I realize this is an inefficient way to do this, but I don't have another pot big enough to heat my jars (the only other one that is close currently has my hot vinegar solution in it).
Preheat the jars with hot tap water, and then just dump them in the boiling water (with tongs or other appropriate utensil, of course).
