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 large pot of boiling water. This process kills off any bacteria and other microorganisms that may be present in the food, creating a vacuum seal that prevents new contaminants from entering the jar. The water bath canner is typically a large, deep pot with a rack in the bottom to hold the jars off the bottom of the pot. The pot is filled with water to a level that covers the jars by at least an inch, and then the water is brought to a boil.
The jars are left in the boiling water for a specified amount of time, which depends on the type of food being canned and the altitude at which you are canning. During this time, the heat from the water penetrates the jar and kills off any bacteria that may be present. As the jar cools, a vacuum seal forms, which prevents new contaminants from entering the jar. This seal is what allows the food to be stored at room temperature for long periods of time without spoiling. It’s a simple yet effective method of preserving food, and with the right equipment and a bit of practice, anyone can master the art of water bath canning.
