So I decided to try my hand at hamburger jerky because my stepson and I like Jack links jerky. I used the recipe from masterbuilt's site and smoked with mesquite for 5 hours at 140. I had difficulty keeping the tbs going. So I would turn the temp up, get the smoke going and turn it back down. Three hours in I realized that I should have left the vent open all the way. Call it a learning experience. I lack a jerky gun at the moment, but after the success today (meaning the missus is happy) I may get the jerky gun soon.
