|Each box contains a dozen BPA free lids and rubber rings.|
There isn't a whole lot of difference in canning with these as opposed to self-sealing lids. They involve using two pieces instead of one, with the rubber ring first, then the lid, then the screw band.
|Canning the bone broth I made a few days ago.|
Rubber ring first, then the Tattle lid, finally the screw band.
The biggest difference is that they must not be screwed down tightly before going into the canner. The jars must be allowed to vent, so after tightening I loosened about a quarter of an inch turn. Upon removal from the canner, then they are screwed down tightly. To make sure the seal completes they must be allowed to cool completely, 12 to 24 hours.
The next day it was time to remove the screw bands and test the seal.
|Testing the seal by picking the jar up by the lid|
This is done the same way as conventional self-sealing lids, but picking the jar up by the lid. If it holds, the seal is good. Out of 17 jars I only had one that didn't seal properly.
Since they are reusable, I didn't want to write on the lid. Usually I make a note of the contents and the canning date. Instead, I used a permanent marker to write on the jar.
|Contents and date written on the jar with permanent marker|
This isn't permanent permanent, it will scrub off. I just find it a handy way to write notes or dates on jars. Of course if the contents are dark in color, I'll have to squint to see what it says. Also, storing with the screw bands isn't necessary. I do it because otherwise I'd have to find a place to store a big box of unused bands.
|Prying the lid off gently with a butter knife.|
Removing the lids is easy too. Care must be taken not to damage the rubber rings, but that's easily accomplished by prying it off with a butter knife.
My conclusion? I'm absolutely won over. I know the rubber rings will wear out and have to be replaced from time to time, but that seems better than disposable canning lids, any day.
