The Can Cooker 4 Gallon Convection Steam Cooker Bundle w/ JR Companion 2 Gal Cooker 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 Can Cooker can be heated on a number of heat sources, from stovetops to campfires to bbq grills. The high-temperature silicone gasket helps trap the steam that is released when the water is heated to the boiling point, cooking your food thoroughly and efficiently. Cooking with the steam will keep your meals tender and keep food from sticking the sides of your cooker. The Can Cooker is loaded with features to help keep you safe while preparing your meals. The riveted heavy-duty handles are stout and secure, for easy transportation from the heat source to the dinner table. A vented lid helps relieve excess pressures and the safety clamps keep the lid in place. The Can Cooker has a capacity of 4 gallons and can feed up to 20. The included CanCooker JR Convection Steam Cooker has a 2-gallon capacity and can feed up to 10 people at a time.
