Abstract: A cooking appliance with an integral drain is disclosed that has at least one burner and an inclined surface adjacent to the burner that terminates with a strainer and drain pipe. This allows one to drain a pot of hot liquid without the dangers of transporting the pot of hot liquid from the stovetop to the sink. A novel drain pot may also be used with the cooking appliance with an integral drain. The drain pot is a cooking vessel with a drain valve. The drain valve can be opened to allow hot liquid in the vessel to drain directly into the integral drain of the cooktop without the need to move or lift the pot. The cooking appliance with an integral drain serves to drastically reduce the risk of burns from mishandled, dropped or spilled pots full of boiling hot liquids such as water.
