In this article, the author explores the history and perception of canned food. They mention that the French government issued a challenge in the late 18th century to inventors to find a way to preserve food, which led to the development of heat-sealed containers by Nicolas Appert in 1809. The author questions why it’s called “home canning” when people use glass jars instead of cans, and explains that the process was originally called “appertizing.” They also discuss the rise and fall in popularity of canned foods and how they are still a significant part of our culinary lives. The author notes that canned food has a long shelf life and can still bring value even after many years.
