Also known as "beer can chicken", in which you stand a chicken over a 3/4-full can of beer and grill or bake it. The Chief and I tried this for the first time over the weekend. It took a bit longer than we'd expected, but the results were WELL worth the wait - even the breast meat was very moist and juicy. We went with a mesquite marinade mix and added mesquite chips to the charcoal. Can't wait to experiment with other marinades or spice rubs.
I've also learned that a mesquite-grilled chicken carcass makes for some rather funky-smelling but very tasty chicken soup.
