Follow up...I decided to get the butts finished before adding the ribs. Everything worked out great, the butts finished up right on time and went into FTC mode while 2 racks of ST. Louis cut ribs and all the little extra trimmings cooked.
Just before I pulled the ribs from the smoker I got all of the pork out and pulled and bagged (most of) it up. Was it ever tender and juicy. I've become a real fan of the FTC method. I think it really helps the meat retain the juices. Theres nothing worse than slicing a brisket or pulling a shoulder only to see the juices running all over the cutting board.
Again, thanks to everyong for the great advice.
On a side note-learn from this bonehead mistake. Don't try to use whiskey soaked applewood chunks! We visited the Stillhouse at Belmont Farms, Culpeper VA. They had a large baggy of the charred applewood chunks that they flavor their VA whiskey with. Perfect size, I thought. And only 10 bucks, I'm all over that. Whiskey applewood smoked butts...mmmm, mmmm. I'm sure ya'll can guess what happened...about 20 minutes into the cook...
BOOM. long story short there wasn't any damage to anything and I replaced the wood with some dry cherry I had. What I'm wondering is if I let the wood dry out for a while would it be safe to try again or should I just burn it in the fire pit and enjoy the aroma of Virgina whiskey from a safe distance?
