I’ve been wondering about storing cooked bacon in jars.
I mean I’ve bought the jars of bacon bits and they have a one year shelf life stamped on them, probably good for longer than that.
And In cooking bacon, you take it to temps that NOTHING could survive. Not any of the normal bugs that cause food-borne illnesses, not botulism.
If it was cooked to a good crisp, set on paper towels to drain a bit, and then the slices put into jars, it ought to last a heck of a long time.
I know lard, as long as it is unopened, has a long shelf life 5-10 years or more...
put your cooked bacon into canning jars and process it for whatever time and pressure your cooker calls for for meat.
