I have only tried smoking some polish sausage a few times and here is the problem I 've had.
The casings turn out really tough!
I smoked them at about 150 or so for at least 4-5 hours as per the instructions I had.
I soaked the natural casings in water with a little vinegar for about an hour prior to stuffing..
Did I do something wrong.
Any help is appreciated because I'd like to try again soon.
