Abstract: The steamer device of the present invention is an elongated enclosed structure which is configured to receive and contain an amount of steamer liquid. The steamer device is placed within a bed of heated grill briquettes below the grilling surface of a grill assembly. The steamer device uses the heat from the briquettes to evaporate the steamer liquid and create flavored steam. Steam release openings formed in the enclosed structure direct the steam out of the device and towards the grilling surface to flavor the food being grilled on the surface. When the grilling surface and steamer device are enclosed, a steam atmosphere is created which flavors and moistens the food while providing a quicker cooking time and reduced flaming. The steam device does not alter operation of the grill nor prevent the natural juices of the food from falling onto a heated surface and being burned or evaporated to further flavor the grilled food.
