Hi all. New member here and new to sausage making. I made some bratwurst and dried them overnight. I smoked them today. Started at 140 degrees with hickory smoke for an hour. Went to 160 with smoke. Somehow I messed up step 3 on. So I set the temp at 170 and the food probe at 165 finish temp. Seemed to take forever to reach temperature. I changed the temperature to 185 after 5 hours. The sausage finally reached 165 after 6 hours. Plunged the sausages into an ice water bath. The casings are tough and seem dried out. Any ideas where I went wrong?
