A couple of things jumped out at me. First, they covered the hole in the Bundt pan?? Wouldn't you want hot air to flow through? Loved this little ditty in the instructions - "Place the chicken in the middle of the Bundt pan, breast side up." In an upright chicken, define "breast side up??"
To me, it sounded like the main purpose for doing this was to baste the veggies in the pan with the chicken drippings, not so much about a better way to roast a chicken.
