I want to make sure that there was first an understanding about a few basic features of a pressure canner that hold true for all of them. First, this is a canner and not a cooker. They are specifically built to withstand the type of canning that we are doing and have features that make it easy for a canner to do any safe recipe. A pressure cooker is a pot that has a single weight on the top that is set for 15 lbs of pressure. It looks like the pot at the right.
Most of the recipes do not require this much pressure for canning and you will over cook your recipes and not get the quality product you desire.
Second, all of the specification for the pressure canners are based on the fact that you will be using a regular mouth canning jar and not a wide mouth. I do know that you will lose the standard capacity in the pressure canner if you use a combination of wide and regular mouth jars. Please take that into consideration and don't freak out if you don't get full capacity when your canner arrives.
Third, all of the pressure canners either have a dial gauge
Below is a chart which contains the research that I have done for three of the most popular brands available on the market. These can be found at a "few" retail locations but all are available online and a link below to a reasonable price site that I found. That price shown is without shipping and handling as some of the sites I looked at had free shipping for the more expensive brands.
I would love comments following this post if you own one of these canners to help out the other readers in making a decision. Many of you know which one I use, but to be fair I want to be impartial and see what the feedback is on these products.
