Shelf-stable canned goods -- heat-sterilized fruits, vegetables and meat preserved in sealed containers -- have been part of everyday American life since the mid-19th century. While industrial canning utilized metal tins and mechanized processes, other forms of canning came to rely on glass bottles and the domestic labor of women. But even in the early 1900s, the practice had multiple meanings: for some, home canning was old-fashioned, inefficient or embarrassing. For others, it was a valuable skill to be displayed in public and mobilized in times of need. In today's contexts of economic instability, automated systems, and cultural and environmental change, do-it-yourself canning is experiencing a revival. The process can be a way to recall people and places, to perform authentic or esoteric taste, and to enact abstract values such as stewardship or self-sufficiency. In the 21st century, more people are canning their own food, and more are writing about it. However, the histories of canning that crop up in everything from food magazines to microbiology textbooks have been strikingly similar: they invariably celebrate a single "father of canning" -- a man depicted as a chef and/or scientist motivated by military concerns -- and consistently warn against relying on "grandma's" methods.
