The CanCooker Original CanCooker takes the cattle drive tradition of cooking in a cream can and revolutionizes it with the power of steam to cook a healthy meal on any heat source. Built out of food-grade anodized aluminum, the portable CanCooker can be heated on a number of heat sources, from stove tops to campfires to BBQ grills. The high-temperature silicone gasket on the CanCooker helps trap the steam that is released when the water is heated to the boiling point, cooking your food thoroughly and efficiently.
