Got a wild hair last night to try a butt in the smoker today. Store was closed so running there as soon as they open to grab a small one, hopefuflly don't get slapped!! I've never done pulled pork befor and was hoping to have it for dinner tomorrow night. My question was how long does the rub need to sit befor I start smoking?? I usually let my ribs and brisket sit at least 24 hours but I'm worried about cooking timie and not having it ready for dinner tomorrow night.
