Hi, cookin a turkey. Temp? Time Per Lb? Test temp in thigh?
Epicurious has a great chart for turkey doneness, taking into account turkey size, oven temp & time: http://bit.ly/dMQo7M But it's best to take the internal temperature too -- you'll want to hit at least 150 in the fleshy part of the thigh (the temp will continue to climb as it rests).
