Canning Chicken

I have a pressure canner--I actually have two; one bought last summer and one bought a few years ago.  The picture is of my largest, an All American 921 that can hold stacked pint jars.

I have always planned to take up pressure canning, but until now haven't.  I'm not concerned about the pressure canner blowing up.  The All American has six screw-down locks, additional lugs to prevent the lid from blowing off if the main locks somehow fail, and a overpressure plug that will blow out at some point if pressure increases.  And I'm now under 1000 feet in elevation, so am able to can at 10 psi instead of 15, thus reducing the potential problems with pressure, anyway.  My main concern has been food safety.

I've gotten very comfortable with canning acidic foods, but botulism poisoning would be a show-stopper.  But it is also very rare (only 17 cases of foodborne botulism reported in 2018).  So whatever people are doing to can low-acid foods seems to work reasonably well--and I assume that the directions at the NCHFP site are designed to be safe at the > 99% level. However, the site also has horror stories.

All this being said, procedurally, pressure canning of most things is pretty easy--much more so than peach preserves, for example, which require a number of steps to get to the point that something is ready to go into jars.

For chicken, it's very easy.  In this first attempt, I canned some boneless, skinless chicken breasts.  I just cut the raw breast meat up into small pieces and packed the pieces into the jars.  I got about 13 ounces in each jar, leaving about 1 1/4" headspace (to the 'freeze' line).  The processing time is 75 minutes for pints. I processed them for 80 minutes, just to be sure the jars got to 240 degrees throughout.

If you look around online, you'll find some sites that suggest adding liquid to raw-packed meat jars before processing.  In my case, that would not have worked.

As the picture below shows, the jars are pretty full of liquid.  This may be because of the chicken I used--Great Value from Walmart.  The package said something about how the chicken may contain brine, much like the turkeys for sale around Thanksgiving.  The NCHFP site notes that there usually isn't enough liquid in raw-packed meats to cover the contents of the jar, but it worked fine with my low-grade chicken. As a side note, I'd intended to add 1/2 teaspoon of salt to each jar, but forgot--nonetheless, when I opened a jar the next day to sample it, it seemed as though it was seasoned just fine--because of the brine, I assume.

Last summer I didn't do any canning, partly because the house was hot and the thought of running boiling pots on the stove for a long period of time wasn't attractive.  That will definitely be a factor this summer, as well, which is fast-approaching.  I do have an outdoor camp stove with two propane burners that I plan to try using (though the NCHFP discourages this; it seems that it should be doable without causing damage to the canner since the body is so thick--and burners can always be turned down).  All this being said, the big canner seems to absorb and internalize most of the heat, not radiating much out into the room.  Some steam escapes, but it's less than with a boiling water bath or atmospheric steam canner.

Going forward, I expect most of my canning to continue to be non-pressurized.  However, it's nice to have the option to can low-acid foods, as well.
