Hi, Started my first butt this morning about 6am. After 4 hours I inserted the probe and am at about 146 degrees. So far so good. Question is this: I have been applying Hickory smoke the entire 4 hours. I add a couple of chunks each hour and it seems to keep a nice TBS going without a huge amount of smoke. So, how long should I do this? I plan to foil at about 160-170 to finish to 200. Should I apply smoke until I foil? I also have a second question. When probing for tempp, I know that I should avoid bone and fat pockets. So, would I expect a low reading or high if I hit a fat pocket?
