How important is headspace in canning?
Answer. Headspace is the distance between the surface of the food and the underside of the lid. Leaving the specified amount of headspace in the jar is critical to assure a vacuum seal. Too little headspace can cause the food to expand and bubble when air is pushed out from under the lid during processing.
