Camerons Professional Cookware Smoker Bag for oven, grill or campfire use. Use with fish, poultry, beef, pork, vegetables and game meat. The wood chip flavoring is already inside, sealed between the bottom two layers of foil, and held in place by natural wood syrups, so preparation of your meal is a snap. The fish, poultry, meat, tofu or vegetables can be placed in the bag with seasonings to your taste – no fats, oils or salt need to be added. Fold the opening end three or four of times to seal and press firmly. Place on the medium high barbeque grill or on the bottom rack of your 425 degree oven for the times given. The bag will balloon while cooking. Remove and cut the top open with a sharp knife for your moist and tasty smoked meal. Serve food from the foil bag, and then toss away the bag. NO CLEAN UP AT ALL.
