Humor me by listening to my long tale of woe.
I started smoking sausage severl years ago with a WSM - could not learn to control temperature, and smoking sausage was a failure. Purchased a MES and experienced the same overshoot of temperatures and fat out sausages. Gave up, but kept my Weber for grilling. Purchased a RecTeq RT-1250 pellet grill, and it works quite well for low-and-slow cooking, but the lowest temperature setting is 180℉. Too hot for sausage.
Now I have a slightly used CookShack MSO25. It works quite well, have made Jerky with it, and today cooked sausage with it. Phoenix temperature at 9:30 AM on start was 103℉, and climbed to 115℉ by 1:30 PM. So, I smoked the sausage with a smoke box, since I cannot get the MSO25 to create smoke at low temperatures. Using learned procedures, I started cooking at 135 degrees, increasing to 150, then to 160, and eventually to 175℉. The sausage internal temperature hovered around 135 - 140 degrees for the entire cook. Shortly after the cooker reached 175℉, the sausage reached 150, and I shut things down after 8 hours and 15 minutes of cooking.
That, to me, seems to be a long time. Your thoughts?
