Check with your local Cooperative Extension Office.. they may have a Master Preserver Course that you can take. Whether you are experienced at canning. freezing, preserving or not, you will learn something.. I took the course last year via the University of Maine and earned my Maine Master Preserver certification. I had been canning for over 30 years, and I came away with a whole new set of skills and knowledge.. Annette No View Farm Rumford, Me
