I've you want to expand your horizons in canning, contact your County or State Extension and sign up to become a Master Canner.
If you want to start off on a small scale, go to the National Center for Home Food Preservation (National Center for Home Food Preservation
) and take their online self-study course in Food Preservation. If you are good you should get through it with 100%.
They and the USDA are the recognized final word on the subject of food preservation, canning, and food safety and if they say it is not safe....it is not safe. No expanding horizons beyond that.
