Oven bag

An oven bag is a plastic bag used for the roasting of meat or other food in an oven. An oven bag helps to keep the food being cooked moist, by trapping the moisture in the bag and preventing it from escaping into the oven; as such, it serves a similar purpose to basting. The plastic used for manufacture of the oven bag must be chosen so that it will not melt at the temperature during cooking and thus spoil the food.
