Canning 101, let’s get started.
Out of the corner of your eye, you see your mason jars sitting in the cabinet. A-ha! You realize that canning is a wonderful way to preserve your food while it’s in season so you can enjoy it after your garden is long dead and the food becomes horribly expensive at the market because it is out of season.
Either method of canning heats the food sufficiently, killing off any bad microorganisms and the vacuum seal prevents any air entering the jar that could cause bacteria to grow, spoiling your food. Canning stops time, locking in that freshness for months, if not years.
