Smokenator Prisms are stainless steel smoker boxes that holds hardwood pellets for smoking food on any gas or charcoal grill. The pellets slow burn to give you that delicious smokey flavor that is hard to achieve during traditional grilling! Smoking prisms are often used for Hot Smoking of foods in conjunction with a heated cooking grill. The prism pellet boxes can also be used for Cold Smoking (cheese, fish, etc.) where the grill is used as a smoking chamber not for cooking.
