I am going to attempt my first brisket tomorrow morning. I am going to inject it tonight and rub it tomorrow morning. I might rub it a bit tonight but I don't want the rub to fall off when it is sitting in the injection juices. I am planning on a 225 degree UDS smoker and will foil it once it reaches 165 ish then I will take it up to around 200 degrees and foil in the cooler for a few hours. I have a small 6 lb pretty lean flat from sams club. Do you guys usually figure 2 hours per lb roughly to give you a rough guess on finish time? Just trying to figure out what time I need to get things going. This flat is only around 2 inches thick so it isn't very thick so I am thinking 2hr per lb is a pretty high guess on time in this instance.
