I'm just about out of time before a big party, so I had to settle for a 7 lb. flat brisket. This will be an all day cook. I will be doing two pork butts and the brisket as well as ribs later in the cook. Everything will be low and slow (about 225-240). So my question is how long on the brisket? I don't cook to temperature normally, just to doneness. Would you pull the brisket and foil it or just let it rest and then slice it?
