A cauldron is a large, deep pot for cooking over an open fire, traditionally round-bottomed with legs or a handle for suspending from a tripod. It is the ancestor of the stockpot, used for centuries to simmer stews, soups, and porridges for households and communities. Cast iron versions distribute heat well and last generations. While modern kitchens have replaced it with purpose-built ranges and pans, the cauldron survives in outdoor cooking, traditional festivals, and its powerful cultural image. Its design principles, generous capacity and even heat, live on in every large cooking vessel used for batch feeding.
