unless you want to scour the oven racks after cooking, do not put the bird directly on there. it will leave a bunch of junk, gunk and oil that will go rancid and smoke next time you cook.
agree with the above about spatchcocking.
As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
– Ernest Hemingway
