Well second smoke on my WSM, a brisket flat from Sam's. Started WSM last night around 7pm, and put brisket on at 8pm. Pulled this morning at 8am with internal temp of 192F; turned out fantastic. I used cherry and mesquite wood chunks and did not foil, just let her run. This was one of the best tasting smokes I have done. I was really nervous about it being too dry but it turned out great. I used sand in the water pan this time instead of water this time; but I seemed to have problems holding temp. It peaked at 300F at about 1am, I had all the bottom vents closed and ended up turning the top vent partially closed. I was hoping to keep it around 225F, but it still turned out good. I am wondering if I did not start out with too many lit coals, I used about 3/4 of a chimney of lit? But the WSM ran all night and still have coals left over this morning. Thanks for looking!
