Typically called a "water bath canner" it consists of a large cauldron style pan with a removable rack to hold canning jars. Once sterilized canning jars are filled with food items and brand new jar lids are placed on each (with reusable rings finger tightened around the top of them) they are placed in the rack and lowered into boiling water. Most items call for 20 minutes of boiling - directions are given with canning jars - and a specialized jar remover tool can be used to take them out one at a time and set aside to cool. As the filled jars cool the lids will vacuum seal to the top of the jars forming a slight indentation on the top and a "pop" sound. The food is now preserved for storage without refrigeration. The appropriate food for this type of canning is jellies, jams, pickles and NOT meat containing items which are "pressure canned".
