The 2 8lb butts have been on the smoker for about 2.5 hours and we are sitting steady at about 240... I have a large foil drip pan below the butts, but I just lifted the lid for the first time and the pan doesn't have any liquid in it. The butts are crusty from the dry rub, but no liquid seems to be dropping down. This is my first butt on my new Oklahoma Joe offset smoker, is this normal?? Any hints/tips/feedback etc would be great.
