Try as I might I cannot get my casings tender or have them have that pop I am on my fourth or fifth round of sausage and the casings always turn out tough and chewy. I have tried rinsing well ( inside and out ), soaking a long time ( up to an hour or so ), and adjusting the damper on my electric smoker ( closing off as the smoking progresses ) ; changed different brands of casings and I just can't get it right, Always tough and chewy. Can anyone please give me some more options on this problem ? Thanks and I love this forum, I have learned a lot.
