Canning pots are large, heavy-duty pots designed specifically for the process of canning food. They typically come with a lid and are used to heat jars filled with food to preserve them for long-term storage. The pot usually has a rack inside to keep the jars off the bottom, allowing water to circulate evenly around them during the canning process. These pots are often made of stainless steel or aluminum and can hold multiple jars at once. They are essential for home canning enthusiasts and are used in conjunction with other canning supplies, such as canning jars, lids, and canning tools.
