In both of these videos by Paul’s Rule of Thumb (YouTube), we watch a thorough explanation of how to use Harvest Guard Reusable Canning Lids. Paul takes us through an explanation of the product, the prep work, gives us some general canning advice, then shows us how to apply the Harvest Guard Reusable Canning Lids to the jars, a step that he notes as being different from traditional canning lids. He shows us what to do when the jars come out of the canning process and shows us the result. Paul also explains to us what went wrong when he had a seal failure. He states that he is pleased with the product and will be ordering more in the future.
