Arnaud, Gus talked about reheating pulled pork. I want to share a technique that I developed for heating pulled pork. Essentially, I steam the pulled pork. I bring about half an inch of liquid to a boil in a large pot. I prefer to use apple juice, but water works. Put my pulled pork in a steamer basket, cover, and in about 7 - 10 minutes the pork is hot. I like this approach because it is fast. Since you only have a little bit of liquid in the bottom of your pot, it comes to a boil quickly. Turn off the burner and leave the pork for your second serving sitting in the steamer basket and the meat stays nice and warm. Almost like having an Alto-Shaam in your kitchen.
