Since so many of us are gardeners, I thought I would share some info to help some newbies in canning. Please feel free to add anything I might have missed.
Equipment:
Water Bath Canner (Large pot)
Can lifter (for lifting hot jars out of canner)
Canning funnel (this is a large mouth funnel)
Canning Jars
Canning Lids (not resusable)
Jar rings (holds the lid on the jar while processing)
This will take care of most of what you will be canning. Some vegetables (low acid) require a pressure canner. But if you're canning tomatoes, making pickles, etc, then the water bath canner is much much cheaper and is used more than the pressure canner anyway.
You can get a kit on Amazon to get started that includes the canner and all accessories as well as the Ball Blue Book
