In order to successfully smoke food, you must maintain a fire (nearly) every day. The surprising thing is that it worked one time, which means that the villagers maintained a fire for you on that attempt. I did not know they would do things while the player is away from the village.
In my playing I have had success smoking meat but have not left the cabin without a heated fire for more than an overnight trip a few times during smoking.
