We make it differently and don’t have problems. What we do is stuff them in the fibrous. Then we cold smoke them in a smoke house (it is like an old wooden shed on the farm that breathes a lot and is not insulated). Then we cook them in a kettle with water. Then they hang a bit to dry. Into the vacuum seal bags and freezer. When they thaw out the fibrous casing is usually loose and comes right off. With this method I think you get a lot more moisture into the product though. I should mention that we don’t use a commercial spice/cure mix. We have our own recipe and we use tender quick to cure.
