To can food at home, you combine canning safe glass jars, lids with rubber gaskets, food that's safe for canning and the right heat processing. Home canning allows you to preserve almost any food – even entire meals – but you need to follow the rules. I do the bulk of my canning during harvest season, but can fire up the canner any time of year. One trick I've taken advantage of is to toss whole fruit (like tomatoes) or fruit puree into the freezer, and then finish processing when the weather has cooled. In this post I’ll discuss how to can food at home safely, basic equipment for home canning, and general canning tips.
