01 - Heat the grill or barbecue to a medium temperature to ensure even cooking.
02 - In a mixing bowl, combine ketchup, apple cider vinegar, brown sugar, Worcestershire sauce, Dijon mustard, smoked paprika, garlic powder, and black pepper. Whisk until the mixture is smooth and fully blended.
03 - Place sausages on the hot grill. Cook for 10 to 12 minutes, turning regularly with tongs to achieve uniform browning and thorough heating.
04 - Brush sausages generously with barbecue sauce during the last 5 minutes of grilling, turning frequently to glaze and caramelize all sides.
05 - Arrange cooked sausages in buns if desired, garnishing with additional barbecue sauce, onions, pickles, or coleslaw to taste. Serve immediately.
