Humans have been using a variety of techniques to preserve fresh food for millennia. Once upon a time, the only way to preserve something was to use copious amounts of salt. Long before refrigeration and easy access to ice existed, people started using pots, jars, and–eventually–cans to allow ingredients to last long after the harvest season. Though canning is a relatively simple science, it does take a lot of technique and practice to perfect. Fortunately, it's relatively easy to learn and modern technology has made the art of canning accessible to anyone looking to connect with their roots or make the most out of their own garden harvest–whether for necessity or want. In our quest to learn about the canning process, we tested some canning kits and compiled a list of what we considered to be the best options available. Check them out here.
