The Tattler lids are reusable year after year, are BPA-free, and made in the USA! I really like the idea of using them again and again which reduces waste and is one less thing to buy. There's nothing worse than getting all your supplies on the counter and realize you are two lids short! I purchased a dozen of these narrow mouth lids and bands for $8.00 and wide mouth lids and bands for $10.00 which equates to less than $1.00 per lid. The downside of the Tattler lids is that they are made of plastic, a petroleum product. Without doing a full lifecycle analysis (who has time for that?), I still think the Tattler lids are more sustainable for the fact that they are reusable and the food shouldn't be touching the plastic lid anyway.
I canned 35 quarts of green beans with these lids and they successfully sealed! I still have a stockpile of metal lids that I will save for jams, peaches, applesauce, and tomato soup that I will give away to friends.
Tattler lids are very easy to use. Simmer the lids and rubber rings in water until ready to use and...
I also have two of these old-fashioned jars with the rubber ring and glass lid held together with a metal clasp. These are rare, and if you're lucky, the lid will not have any chips and cracks. In terms of sustainability, I think these would be the number one choice, but the user would need to take extra care with the glass lids and make sure the metal clasps don't rust. Speaking of rust, remove metal clasps and rings when storing. I don't know why people think that if they remove the metal ring, the lid will unseal----remove the ring to keep it from rusting! The rings will last a lot longer this way.
I always think it's sad to see the beans go from bright green to a dull green after they come out of the canner. A picture of before and after...
