Got a stuck canning ring that won’t come off after canning so you can check your seal?
Sometimes sugars or other solids from food can seem to cement a canning ring on.
Don’t fight with it. Soak it.
Stand the jar upside down in some warm water, and in a few minutes the canning ring will loosen so that it can be removed with normal, gentle force.
With the ring off, check your seal by gently lifting the jar by its lid.
All canning rings should be washed before storing them away, but ones that were stuck on seem to always require an extra good wash.
