I purchased the 40" Masterbuilt special at Sams, and sorry to say for my first run, I didnt have too good a luck with a brisket. I tried to follow all the advice here, but I guess I did something wrong. Got up at 5:00 this morning and put the hickory chips soaking and turn the MB on. (seasoned it yesterday for 4 hours). Set at 225 and added boiling water Also at this time I seared the brisket on an infrared searing burner and got it good and crispy on the outside. Added the chips after 30 mintues and it was smoking in about 10 minutes. So 40 minutes in the smoker was about at 210, so I added the brisket (cut into 2 pieces). Let it smoke about 3 hrs and it got to 160. Then wrapped in foil and put back in smoker. It got to 190 in about 1.5 hrs. I let it rest for 45 minutes in the foil then uncovered and sliced. It ended up not as tender as I expected, and there was not a visible smoke ring. I added wood about every hour to 1.5 hours. Any suggestions to my flop?
