Rub generously into a bone in pork shoulder. Get your favorite grill or smoker up to 225 degrees and smoke it over very indirect heat for 1 1/4 - 1 1/2 hours per pound of meat, but no less than 10 hours. I also mop with a vinegar/oil/hint of Tabasco mix every once in a while. Shred with two forks, and sprinkle more rub into shreds.
For ribs, pull off silver skin and rub well. If you’re making baby backs, grill/smoke hybrid with indirect heat 250-300 for 4-5 hours. And for spare ribs, soak overnight in pickle juice and then do the above listed, but at 225 degrees for 6 hours. This rub also works quite nicely on pork loin or chops. Pan, oven, grill, you name it.
