that is what I have almost always done. It breaks the vacuum. Sometimes I'll do the hot water on the lid thing (especially if whatever is in the jar is syrupy like molasses, or has a high sugar content like vanilla, particularly after it had been opened previously and sealed itself shut again). But tapping the jar with its lid on the edge of a counter will generally do it. I do have one of these in case none of the options work -



It is configured as adjustable to do the larger diameter lids down to many of the smaller ones.

For some of the smallest ones (mostly bottles with small lids like flavorings), my go-to is a nutcracker!
