A few weeks ago, I was reading Kellene Bishop's Preparedness Pro blog and she had posted about reusable canning lids. A number of readers commented on the lids, and I recommend that you check out the blog, AND the comments. Initially, when I saw these re-usable lids, I was all enthused, and thought I would like to have some. This seems like it might be a useful item to have on hand.
However, I'm put in mind of a few recent blogs I read that asked if you are going broke prepping. It seems like there's always someone coming up with some new "must-have" preparedness product, and people flock to purchase them, which is fine if you have the money to spend.
However, for those of us on a budget, these new "must-haves" can be depressing to contemplate.
I reuse my metal ones. And I can pick them up at the dollar store very economically. For the price of one flat's worth of re-usable plastic lids and rubbers, I can pick up 10 or more packs of the tin lids. If you carefully inspect a used tin lid, you can readily tell when the sealing material is gone and not suitable for reuse. And even a new lid can fail to seal, which is why we test the seal after cooling.
So, while I think it would be wonderful to have the plastic re-usable lids, I believe that I will stock up on the tin lids.
