I just made up my last batch of plums (jam) from last years crop.
I left my canning pot in Nevada and didn't want purchase another one.
I have roster pan but it is not tall enough to cover the 1/2 Pint jars.
I found another pot that would work but, I could only do 6 jars at a time.
Do the jars have to be standing upright in the sealing process?
Do they have to be covered with water?
I could have put the 12 jars in the roaster pan at one time. But, would have only been able to fill the warer to the bottom of the lid ring
