It is almost canning season! So today I researched freezer vs. canned jam. The difference is that freezer jam is not cooked. This makes it a lot easier and simpler than canning jam. But the flavor is definitely different.
When canning, I recommend getting an actual canning book. I have the Ball Blue Book. By following the recipes in this book, I know the food meets the USDA's requirements, and will be safe. I don't know if a recipe from a website, friend, or family member will be safe.
When making a freezer jam, you don't have to worry about safety. Anything can go in the freezer, and as long as the freezer is cold enough, it will be safe to eat.
