Got up at 4 am to start my brisket. I rubbed it down before I went to bed with yellow mustard and Jeff's Rub. This will be only the second brisket that I have smoked and the first time trying Jeff's Rub on one. The brisket is only 6.2 lb. but I decided to start it early because it is supposed to be cool and very windy here today. So I'm sure the smoker temp is going to fluctuate some today. Also, what is the minimum amount of time that I should let the brisket rest after cooking?
