I am going to smoke some beef snack sticks tomorrow. I have been reading different things about it. They are 100% beef and 90% lean meat. Question 1) why do people heat for an hour or so before they smoke. question 2) what do posters mean that the fat will melt out or to the bottom if you get it to hot? I would like to make them a little dryer. question 3) if I stuff the stick more lose will they shrink up more and become smaller (which is what I want) Any help would be awesome.
