Ok. The weather finally warmed up and the brisket has been on for about 45 minutes. Everything is good. I think it'll be done around midnight or so. My question is this. I'm going to put in a cooler with towels before I go to bed. The plan is to eat it for Sunday dinner. When I take it out of the cooler and refrigerate it, should I slice it then or when I reheat it? Also, what is the best way to reheat it? Pictures will be coming. Thanks guys.
