Here are four standard methods use to reheating a pulled ground pork. Reheating in a microwave: Place the pulled ground pork in a container that is safe to use in a microwave and cover it. Use safe covers such as wax, paper towels, or a domed plastic or glass container. Allow the microwave to heat the food at a medium or low setting to preserve moisture. Kitchen oven reheating: While the oven heats at a moderate temperature, wrap the ground pork in a double layer of foil. Add a few liquids of choice before covering the foil. Use apple juice, stock, white wine, water, or beer. Place the wrapped ground pork on a baking pan until the internal temperatures reach a high level. Remove from oven using oven-proof gloves and serve. Use hot water bath: Place cooked ground pork into vacuum-sealed bags. Chill in ice water for around 45 minutes until it freezes. When you want to eat, bring a large pot of water to high heat. Immerse the vacuum bag for 45 minutes for every inch of thickness. When it reaches high temperatures, open the bag, shred the heated ground pork, and prepare for serving.
