Ive been doing a lot of smoking on a Weber 22 lately. Ive noticed that my cook times are less than the suggested time. Im using Kingsford and adding wood chips. I have a thermometer inside (not in the lid) and keep the temps at the suggested temps. The stuff comes out great. So my questions are do you think my thermometer is off? Whats the best thermometer I can get? Should I even worry about it?
