Set your smoker up for 275. Place cast iron pan with plenty of butter in it in smoker until the butter is melted and pan is warm. Place steaks in pan snd cook until 115 temp. Turn them at least once. While they are cooking get grill HOT. Once steaks are at temp remove AC and place on hot grill for about 2 minutes a side. After steaks are seared remove and place back in cast iron pan. Cover with foil and place on counter four 10 minutes. Also the drippings in the pan go good over baked potatoes
