A whole chicken is roasted on the grill sitting over a beer can. It's an easy technique, just as it sounds, and one that any novice outdoor cook can handle. Soda or juices can be substituted, but beer seems to be the most talked about. The beer steams the chicken, but the meat doesn't take on the flavor. And the indirect, medium heat produces a crisp golden skin.
Flavoring comes from the spice rub mixture.
Use your favorite. The spice rub can also be sprinkled on the skin of the bird. Barbecuing a chicken this way also allows the fat to drip away while it bastes the meat. Make sure you set the grill up for indirect heat. This method allows the heat to circulate around the chicken and helps create crisp golden skin.
