My first experience on a UDS was this last Sunday. I had borrowed a UDS from my boss and had picked up a big prime packer weighing 18.9 lbs before trimming. It had alot of fat. Fired up the UDS minion style and had it pegged at 270 with two lower vent holes wide open and top vents wide open. Put brisket on fat cap down at 6:30 pm and ran some errands. When I came back still pegged at 270. Opened a third hole and bumped the temp a little. Opened the fourth and temp got up to 340 and stayed. When it hit 160 internal I flipped it and put it in a large aluminum foil pan, and sealed top with foil. When it hit 210 internal I took it off (about 12:30 am). Six hours total cook time. Half hour rest then sliced and off to bed. Best brisket I've smoked. If you use a foil pan, be careful not to spill the boiling drippings like I did. Next time I'm wearing my fryer gloves!
The next afternoon I chunked up the point, fired up my miniwsm, and put the chunks back on in an aluminum pie pan for another two hours with some extra rub. Resulted in my first successful burnt ends.
Unfortunately I will have to return the UDS soon, so I've started gathering parts to build my own.
