Pork tenderloin grilled in a delicious barbecue sauce
Swapping the bottled barbecue sauce for hoisin creates a much sweeter, denser glaze that clings aggressively to the meat during high-heat cooking. Soy sauce and toasted sesame oil anchor the base profile, demanding precise measurement to prevent the heavy fats from overwhelming the delicate pork. When preparing the marinade, whisk the ginger thoroughly into the liquid components so fibrous clumps do not adhere unevenly to the exterior surface.
Pork tenderloin is exceptionally lean and dries out rapidly under direct flames. Submitting the meat to a six-to-eight-hour marinade bath allows the sodium in the soy sauce to break down outer muscle fibers, retaining moisture before heat hits the protein. Divide the liquid reserves strictly beforehand to avoid cross-contamination between the raw meat soak and the final table-side dipping sauce.
Maintaining a medium-hot bed of lump coal mixed with hickory wood delivers the ideal smoke profile without scorching the sesame oil. Turn the tenderloins every few minutes while brushing them with the thinned vinegar mop to build a lacquered crust. Wet wood chips placed directly on the fire pan generate heavy smoke that penetrates the exterior quickly.
Pull the tenderloins off the grates precisely when an instant-read thermometer registers 155 degrees Fahrenheit in the thickest section. Without a thermometer, press the center of the meat with your index finger; it should feel moderately firm with a slight spring, indicating medium doneness. Rest the meat wrapped tightly in aluminum foil for twenty minutes to let internal juices redistribute fully before slicing on a sharp bias.
