Preheat the smoker or pellet grill to 250°F.
Remove the membrane from your rack of ribs, then coat the entire rack in olive oil to act as a binder for your seasoning.
Season the ribs on all sides with the dry rub and let the ribs sit at room temperature for 10 minutes.
Once your smoker is preheated, place the ribs on the grates and let them smoke for 2-½ to 3 hours. If you are making homemade cranberry sauce this is a perfect time to whip it up!
After 2-½ to 3 hours your ribs should have a nice bark and they’re ready to wrap. Lay down a sheet of foil and add the cranberry sauce, brown sugar, and pickled jalapeños.
Remove the ribs from the smoker and flip them meat side down on top of the wrap ingredients.
Wrap them tightly and return them to the smoker for another two hours, or until the bones are sticking out ½” and they reach 200°F internal temperature.
Carefully remove the wrapped ribs from the smoker. The liquid in the wrap will be hot, so use caution not to spill it.
Let the ribs rest at room temperature for at least 10-15 minutes, then slice between the bones and enjoy!
