Spray the broiler rack with nonstick spray and preheat the broiler.
Broil hens 7 inches from the heat, skinned side down, 15 minutes. Turn the hens and broil until cooked through, 5-10 minutes more.
Meanwhile, prepare the glaze. Combine the cider, jelly, five-spice powder, salt and cayenne pepper in a small saucepan and bring to a simmer. Simmer until the mixture is thick and syrupy, about 7 minutes. Set aside and keep warm (mixture should equal 1/4 cup).
Carefully remove the skin from each hen. Brush about half of the glaze over the hens. Broil until bubbly, 1-2 minutes more. Place the hens on a serving platter and drizzle with the remaining glaze.
