The concept is simple: a whole chicken sits upright on a partially filled beer can (or a dedicated chicken stand) while it cooks over indirect heat. Three things happen at once:
- Vertical roasting keeps the bird upright so heat circulates evenly around the entire surface, including the inner thighs that often undercook when a chicken lies flat.
- Steam from the beer rises inside the cavity, keeping the breast meat moist from the inside out. This is the secret to avoiding dry white meat.
- Fat drips away instead of pooling around the bird, which means the skin renders and crisps beautifully on all sides.
