There are two different types of canning. One is boiling water bath canning which requires no special equipment other than the canning jars and involves submerging the jars in a large pot of boiling water. The other is pressure canning which requires a very specialized piece of equipment called a pressure canner (no that's not the same as a pressure cooker).

The acidity of the food you are canning will determine which method is safe to use. If you use the correct canning method for the type of food you are preserving you can have fun and safely preserving jars of delicious food for your pantry. However if you don’t match the food and the canning method things can get scary (think botulism). Fortunately it’s very easy to get it right and learn how to can safely and worry-free.
