this will sound iffy, but it's actually very good! my BF's coworker told him to try roasting a whole chicken on the outdoor grill with an open can of Guiness inside. the chicken is "standing" upright as it cooks. have it on the grill for about an hour on high heat with the lid closed (or as closed as it can be with the chicken standing up like that), and the chicken comes out very moist and juicy.
