01 - Preheat the grill or barbecue to medium heat.
02 - In a mixing bowl, combine ketchup, apple cider vinegar, brown sugar, Worcestershire sauce, Dijon mustard, smoked paprika, garlic powder, and black pepper. Whisk thoroughly until smooth.
03 - Arrange the sausages evenly on the preheated grill. Cook for 10 to 12 minutes, turning regularly with tongs to achieve uniform browning and thorough heating.
04 - During the final 5 minutes of grilling, generously brush sausages with the prepared barbecue sauce, continuing to turn until all sides are glazed and caramelized.
05 - Serve the sausages hot, placed in buns if desired, with extra barbecue sauce and preferred toppings such as sliced onions, pickles, or coleslaw.
