So I just took my first round of snack sticks off the smoker. They were on for close to 4 hrs at 180. Brought the internal temp of the stick to 165. That outer skin is a a bit tougher than what I would like. I wonder if I went too long or if maybe it’s just the type of skin. I used a collagen casing from Bearded Butchers. Overall the process was pretty smooth and the flavor is great. Just need to dial in the casing part. Any tips?
