Hope that someone can help me out here. While I love to purchase organic, free range chicken, when a sale comes on for a regular old bird for $1.99/lb I just can't resist. I'd like to cook my 7.5/lb chicken via the Thomas Kellar method at 450 degrees. However, his recipe specifies a MUCH smaller bird. Do you think I could get away with cooking it as such a high heat or should I try a different method? Many thanks in advance.
