The period following the cooking of a pork shoulder, during which the meat is allowed to sit undisturbed before being sliced or pulled, is a critical factor in the final outcome of the dish. This resting phase allows the muscle fibers to relax and reabsorb juices that have been expelled during the cooking process. An example is removing the cooked pork shoulder from the smoker and allowing it to sit, covered, at room temperature for a specified duration.
Allowing sufficient time for this process significantly enhances the tenderness and moisture content of the cooked pork. It permits the internal temperature to equalize, preventing a rapid loss of moisture when the meat is cut. Historically, this practice has been recognized by pitmasters and chefs as essential for achieving optimal flavor and texture in slow-cooked meats.
