I cooked my first bratwurst on the WSM and the flavor was great. I threw them on while smoking a meatloaf. However, the skin was very tuff to chew. I used Johnsonville bratwurst and cooked them on the 14.5 at about 275 degrees. After they were done, I sliced them lengthwise and put them on soft sourdough rolls with all of the condiments (sorry, no pictures!). What do I need to do differently to get the skin to break down. Do you recommend a different brand or do they need to be cooked on a hotter grill?
