Hello Melissa, congratulations on your success, I am sure your jams are Tasty. I want to learn and practice storing food, hence it is why I am on this tribe. I have used a pressure canner and there is nothing to fear. The USDA has regulary produced a guide to canning every year that tells you what the pressures need to be brought to and kept at and for how long for each variety of food. The times and pressures are subject to some changes due to the constant evolution of food and the elevation you are at at the time. Sounds like you are doing great with your water bath, you might want to try pressure canning with an experienced person to get comfortable with it, or not.
