Use a whisk to combine the spices thoroughly and set aside.
Trim the fat cap and silver skin off the short ribs, then rub with the olive oil.
Season all sides of the short ribs with the seasoning.
Preheat your smoker to 250 ºF. Then place the seasoned short ribs onto the grill grates. Close the lid and cook for about 5 hours. You will want to add the water and apple cider vinegar in a spritz bottle and spritz the meat every hour during this first 5-hour smoke period.
Now wrap the meat in peach butcher paper and continue cooking at the same temperature or a few more hours until the internal temperature of the meat reaches (200-205ºF). Once done, let it rest for at least 30 minutes before cutting. Tip: if you don't have butcher paper you can use foil instead.
