The changes to smoking of food has made it quite a chore to perform, which is probably a reflection of the reality, but, more importantly, is quite impenetrable to players. There's really a need to explain both how much wood you need to use, how often you need to repeat the burning, as well as for how long you need to do it. None of these steps are intuitively obvious to people not familiar with smoking, and even those who are may well know how to use it as a means of cooking (for immediate/near term consumption) rather than a means of long term preservation.
