>>> Another newbie question about this: the Presto book that came with the canner says to set the jars bout 2 inches apart while they are cooling. Since this would make them cool faster, is it ok to put them closer together? <<<
I remove mine when pressure has equalized and place on towel probably 1” apart and cover “again” with a towel(s), since most time the contents is still bubbling , and I have a tendency to keep the a/c on high hum,, so I dont rush the cool down process..it’s already cooked anyway... hope this helps..
for example I cook a run of london broil cubes at 15 lbs for 90 mins of rocker (pressure) time.. I take about a hour and 1/2 to bring up to pressure and as soon as the 90 mins of pressure rocking/cooking has elapsed, I remove from heat and do the towel cover thing...
it takes about 2 hours or more for the pressure to release..
