Today I took the National Center for Home Food Preservation free educational course on canning. Since it was free I figured it was worth the time to learn something new and double check my knowledge of canning safety and standards.
The reading was pretty brief and included safety information and links to canning competition judging standards. It included how to care for and maintain pressure canners, and where to go to get pressure gauges checked; and water bath canning do's and dont's. Considering it only took about an hour to do all the reading and quizzes, it was well worth the time to learn some new things.
If you have never canned foods, or are unsure of the hows and whys of canning safety, or if you want to branch out from water bath to pressure canning and aren't sure what you need please go sign up for the course. It never hurts to expand your knowledge.
