How to make sure the sealing

Safety buckle on the lid, which you could judge if your canning sealing well. Press down on the center of the lid. Check does it move up and down or does it feel solid and concave Solid and concave means a good seal, movement means no seal. This way to test would help you sealing canning better.

Why Lids Buckled During Canning?

During canning, air trapped in the head space between the bottom of the lid and the top of the food is forced out of the jar. When lids are too tight, the air cannot easily escape so it forces its way out by deforming the lid. This leads to the buckling or crinkling effect.

When you remove your jars from the canner and set them out to cool, steam vapor will continue to be released until the jar begins to cool and the wax ring on the sealing lid suctions into place and creates a permanent seal.

General rule of thumb is to tighten your rings “Finger Tight” – meaning use your fingers, not your entire palm to tighten and there should be another ¼ inch of room to continue turning the sealing ring.
