This stainless steel headspace measuring card is a great stocking stuffer for home canners. Headspace is the unfilled space at the top of a Mason jar between the top of the food or liquid and beneath the lid. The correct amount of headspace is essential to allow for food expansion as the jars are heated and for the formation of a strong vacuum seal as jars cool. Canning recipes will specify the proper amount of headspace necessary. This unique stainless steel card allows for easy and accurate measurement of headspace.

"At the other end of the price spectrum is a stainless steel headspace measuring card designed by food preservation guru Ernest Miller/Rancho La Merced Provisions. It's inexpensive, yet indispensable. I use mine for nearly every canning project I do." - from KCET's "Gift Suggestions from California Master Food Preservers"
