I smoke at 150 until it hits around 140 then usually finish on the grill or in the oven. If I'm doing a pork butt or just want to finish in the smoker I just run the temp up after it hits around 140. As far as the danger zone A smoking temperature of 150 is safe temperature to smoke at for whole cuts of meat, because bacteria grows on the surface of food and smoke has anti-microbial effect. I sear my meat to make sure any surface bacteria is killed. If the food has not been cured, then you need to make sure that you can accurately monitor the cabinet temperature, because you are very close to the danger zone of 140 F. A lot of people say that once you go over 180 your are no longer smoking; you are technically barbecuing. So I aim for 150 as the low and let it bounce to 180. I tend to bounce my heat up and down a little because I end up with better results. It mimics the Texas style that rotates closer to the fire then away again. If you had problems with the texture in brisket, or any tougher cut of meat for that matter, the longer you can keep it between 110 and 120 it helps break down the meat better. Here is an explanation of what happens at certain temps. http://www.scienceofcooking.com/meat/slow_cooking1.htm One thing I've noticed is meat tends to hit a stall point where the temp seems like it sits forever. I smoke through to where it starts to go up again and finish it on a grill or in the oven. You can easily over smoke chicken but it helps a lot to use fruit wood as opposed to oak, mesquite or hickory type woods. one thing you have to get used to with chicken is the longer you smoke it the worse the skin turns out. If you are really into chicken skin then smoking it is not for you. The meat though is outstanding. Wood wise as a general rule I use cherry for chicken, sugar maple for pork, oak for beef and alder or olive for fish. Avoid using bark if you can. raw12 if you want an easy smoke to start with that takes very little time try steak. I get my smoker up to temp and smoke them for 1/2 an hour then finish them in the broiler for 2 1/2- 3 minutes each side. Quick easy and no real time spent. A beef loin can be done in about 4 hours to a temp around 130. I tend to think medium rare is burnt so take that into account. Though smoking beef firms up the mushiness that some people don't like when done rare.
