Open kettle canning is a method of food preservation which involves putting boiling food into extremely hot jars and then sealing them. This method of canning is not recommended by numerous food safety organizations, including the United States Department of Agriculture. However, it can help to understand what open kettle canning is, because this will make it easy to identify and avoid. As an alternative to open kettle canning, cooks should consider canning in a pressure cooker or in a boiling water bath, as these two methods are much safer.
