Page 101 - Barbecue Chicken Made Easy

There are a number of gadgets that hold chickens upright on a wire rack. They work reasonably well because air can enter the cavity and cook the meat on the inside. But the inside still doesn't brown because a bubble of air gets trapped in there.
Vertical roasters have two advantages: (1) They put the legs closer to the heat so they cook faster than the breasts, and (2) the bird just looks cool posing there like a supermodel after you’ve pinned one wing behind its “head” and put the other on its “hip” with its legs crossed.
If you use one of these, get a knife down into the neck cavity from above and open a “chimney” connecting to the abdominal cavity so hot air can travel through from bottom to top.
