It's all done and to be honest, it turned out great.
Started out with two 6-7 pound buts from Sam's. Using a technique I remembered reading here about a brisket that was done quickly, I removed almost all the fat on the outside of the butts. Then I thought I may need a little help making this meat tender, so I gave it a little help. I mixed a tablespoon of tenderizer into about 3 cups of coke and injected both butts. After a good rub and a little more coke in the pan, I put them in the fridge for about 15 hours.
Early this morning I got the Smoke Vault fired up and put both butts in right on grate, no pan. I kept the temp on average of 275 and at 3 hours I was up to 150. I was spritzing every hour or so. I pulled the butts and wrapped them up very heavy in foil and placed in pans. At this time I shut the smoker down and went to the oven. With oven set at 300, it took 3 more hours until both butts reached 200 degrees. I then shut oven off and let them rest in oven for 1 and a half hours. Even with both butts heavily wrapped in foil, both pans were filled with juices when I pulled them out.
This was after 3 hours of 275 degree smoke
After final rest and ready to pull. It just fell apart and the color shows good smoke even after only 3 hours.
All and all I am very please with the turn out. I have a big bowl of the juices in the freezer now separating and will mix up a finishing sauce with it. It taste great. I can taste the smoke, the coke and the rub. Very happy and surprised with the results.
