I'm doing my first fattys today, and I'm switcthing from chips to chunks for the first time. The smoker box that came with my GOSM is too small to hold chunks. So I got a metal cake pan to replace the smoker box. My question is, how many chunks should I start out with so as not to waste wood? And should I soak the chunks or not? Most people on this board don't seem to soak chunks. How long do I have to let the chunks fire up (as compared to chips) before I start seeing smoke? Thanks in advance to all.
