Help! Brisket finished way too early Now with Q-View!

Well, my short term solution was to towel it and stuff it in a cooler.  I was hoping to get some insight as the morning went on.  I had planned on doing burnt ends with the point. I didn't separate it before I put it in the cooler, should I do that before it goes into the fridge or just wait until it comes back out for a reheat later?

Well, it started out as a total disaster.  11 lb brisket finished in 7 hours due to an apparent temp versus reported temp issue and I had a done brisket 13 hours before we planned to eat it.  Thanks dsl1 for the advise on what to do with it.  I left it in the cooler for a few hours before I committed to a solution and then I pulled it out, separated the point and cubed it and put the flat in a half aluminum pan covered both in foil and put them in the fridge.  We were looking to eat at 6:30 so around 3:30 I pulled the point meat back out of the fridge to let it start coming up to temp a bit.  I fired up the smoker again and around 4:00 I started to smoke the burnt ends.  I pulled the flat put of the fridge about the same time and put it into the smoker wrapped in the foil pan with about a hour to go before dinner time.  I had reserved th pan drippings from the morning and after skimming the congealed fat from the top, I reheated some of that and added it to the flat pan before putting it back into the smoker as well.  I wasn't sure what to expect from all of this but it really turned out great.  The reheat took about an hour and when I sliced the flat it was plenty moist and tender.  It sliced great with very little shredding and the burnt ends were delicious. (This was my first time for those.)  Enough of that though, on to the Q-View!

Rubbed and ready.

Sliced nicely



I over sauced these.  Rookie mistake but a learning opportunity too.  They still tasted great though and were a crowd favorite.



Thanks again to dls1.  I owe this successful meal to you and your advise as to what to do when I made such a mistake. I will not be cooking again without the proper tools.  I dodged this bullet but I may not be as lucky if it happens again.
