I have been asked to make my pulled pork for sammies (they are a big hit) for my Niece's graduation party. Gonna do four 8# butts. I want to cook and pull a day or two before the party. After pulling I would put in aluminum pans and store in fridge. Reheat in oven before party in same pans. Normally I wouldn't do this, but the party starts at noon and I don't want to pull an all nighter. Is there any problem doing this? This is a big deal for my wife's family and I don't want to screw anything up so any advice would be great. Thanks.
