Preheat your pellet smoker to 250°F using a hardwood like hickory or oak
Remove the membrane from the rack of beef ribs.
Mix together equal parts garlic powder salt, and black pepper in a bowl.
Rub the mixture onto both sides of the ribs, making sure to cover them thoroughly.
Slather the ribs in Dijon mustard, then season generously
Place the ribs in the smoker for 3 hours with the lid closed
Prepare the spritzing liquid by mixing 1 cup white vinegar and ¼ cup hot sauce
After the 3 hours of uninterrupted smoking, start spritzing the beef ribs with the spritzing liquid every hour until they reach an internal temperature of 203°F (5-7 hours)
Once the ribs have reached an internal temperature of 203°F, remove them from the smoker, wrap them in butcher paper, and let them rest in an insulated cooler for an hour
Slice and serve the smoked beef ribs with your favorite barbecue sauce, sides and enjoy!
