I am smoking my first brisket today (8 lbs). I followed the directions on my WSM and the temperature on the built in thermometer read 225. I was shocked that my meat already reached 150 degrees after 2 hours! I then realized that the temperature on the built in thermometer was reading at least 10 degrees under what the temperature actually was! I tried lowering the temperature (tips on how to regulate the temp would be greatly appreciated) and was able to do so and now after 5 1/2 hours of cooking it's reading 196 degrees. The recipe also called to wrap the brisket in foil at 150 degrees, so I did, but that was confusing since the recipe also called to spray apple juice on it every 2 hours. I just put the apple juice on before wrapping it in the foil. Do you think this is going to come out ok or should I run to the store for a back up option?
