What is water bath canning and how does it work?
Water bath canning is a method of preserving food by packing it into clean, hot jars and then heating them in a pot of boiling water. This process kills off any bacteria and creates a vacuum seal, preventing new contaminants from entering the jar. The water bath canner is essentially a large pot with a rack in the bottom, which allows the jars to be fully submerged in boiling water. The pot is typically equipped with a lid to help maintain a consistent temperature and to prevent the water from boiling over.
The canning process begins by preparing the food to be canned, which can include fruits, vegetables, jams, and other high-acid foods. The food is then packed into clean, hot jars, leaving a small amount of headspace at the top. The jars are then sealed with lids and rings, and placed into the water bath canner. The pot is filled with water, covering the jars by at least an inch, and then brought to a boil. The jars are then processed for a specified amount of time, which depends on the type of food being canned and the altitude of the location. After the processing time has elapsed, the jars are removed from the pot and allowed to cool, creating a vacuum seal as they do so.
