We are having company on Saturday, and I want to try making Beer Can Chicken on the grill. I have what sounds like an easy recipe, with a lot of five and four star ratings from people who have tried it. My concern is, how possible is it to get the chicken to stand up nicely on the beer can, when placed on the grill? Is it likely to fall over? Anybody have any recommendations/cautions to share?
