I have NEVER canned anything in my life but this year plan to grow an extensive garden and don't want any of it to go to waste so....I think (or at least I hope) that I will need to learn. I tried researching canning supplies but didn't realize there are so many options. Pressure cookers or no pressure cookers, various supplies....I ended up a little overwhelmed. So - for a complete newbie to the canning world, can anyone provide me with a list of "must haves" and give recommendations of what brands are best? Oh - and I'm on a budget, so I'm kinda looking for the best low-cost supplies versus the best money can buy. And any hints or tips from experienced canners - perhaps even mistakes you've made so that others can learn from them?
