I need to do a HS graduation party in 3 weeks. I plan on doing 4 - 6 butts and 2 - 3 briskets. It's my son's party so I don't really want to stay up all night. Can I put the brisket, with rub, into my oven for the 1st 6 hours a day ahead then put them into the Lang 60 the next day with the butts? My feeling is that the first hours of cooking are the most important so this may not work out so well. I don't have much time to experiment so any direction would be helpful. I'm not used to cutting corners but someone must have tried this. Thanks for the help.
