The cooking time for pulled pork can vary depending on factors such as the size and cut of the meat, the cooking temperature, and the specific equipment used. As a general guideline, you can expect approximately 1.5 to 2 hours of cooking time per pound of pork shoulder at 190°F, and about 1 to 1.5 hours per pound at 205°F. However, it's always best to use a meat thermometer to determine the doneness of the meat accurately.
