I always pour apple juice over it and sprinkle it with some rub and stir it all in.
Of course, I'm usually portioning, vacuum sealing and freezing it for later. The AJ and rub always benefit greatly upon reheating...making the PP nice and moist and flavorful.
If I'm serving right away, I usually skip the AJ, sometimes not. I find that the AJ helps it from drying out.
