Turn your grill into a self-basting barbecue oven and eliminate tough, dried-out meat. Fill these pre-seasoned cast-iron grill humidifier reservoirs with water, beer, wine or any flavored liquid and place at opposite ends of the grill. Heat activates the release of steam, infusing moisture or flavoring into food. Meat stays tender, and naturally rich in juices from the grill to the table. Ideal for gas, charcoal or rotisserie grills. By Charcoal Companion. Hand wash.
