I made some for the Christmas gathering. First time and I went by the posts I'd seen that say to "smoke for 2 1/2 hours at 225*". I think I should have gone a little less on the time. I'm of the "if you're looking you ain't cooking" school of thought so to me 2 1/2 hours is just that with no peeking. I think on my
WSM 2 hours would have been better, but they still were consumed with much glee.....
I suggest you check them visually around 2 hours until you figure out how they run on your particular smoker the first time you make them.
There are several "how two" and recipe posts on here. Just search for "pork shots" or "pork candy" and you should find them. Short version is 1/2" section of sausage wrapped in 1/2 strip of bacon held in place by toothpick. Then spoon a 50/50 mixture of your favorite rub and brown sugar into the little cup formed by the bacon on top of the sausage. Some people use more sugar, more spice, etc....
