Yesterday even though the weather forecast here was for rain, I had made a commitment to prepare a Brisket for a friends birthday party. I put the brisket on my Weber Smokey Mountain over hickory wood chunks. I brought the WSM up to 250 deg and it ran rock solid at that temp for 12 hours. I ran it with a full water pan. I pulled it off the WSM at 5:00 pm and put it in my cooler wrapped in bath towels to hold for the party. At 8:00 pm I pulled it out to slice it up. It was a bit of a chore today with the weather but the end product was fantastic.
