Canning is something of an ancient art, used to prepare and preserve foods for long periods of time. In modern times it's best used for making jams and sauces, but many people also pickle and ferment foods using canning processes.
The major benefit to canning is that it's easy and you can do it at home yourself, and without any special equipment unless you choose to really invest in the art of canning.
You'll be shocked to learn that foods canned at home can last up to a year, which is pretty impressive. Making your own pickles or jellies at home not only keeps you stocked up on yummy favorites, but you can give them as gifts or even sell them if you've got the entrepreneurial spirit!.
