This might fall under cookware, I'm not sure? Anyway..
I'm going to try canning for the first time (making apple butter for holiday presents), and I have the jars with the two piece caps - but I don't have one of those special canning racks to put the jars into when sterilizing them. Do I absolutely need one (all the instructions mention them), or will carefully placing them into a pot be enough? I guess that they help in getting the jars out of the water, but other than that, is there a real need for them?
