An easy way to make a smoked sausage is to start with a fresh sausage and simply smoke it. Kroger had a sale on mild Italian sausage, and I smoked 2 lbs. at 250 degrees in my MasterBuilt electric box smoker until they reached an internal temperature of 160 degrees, which took about 45 minutes. The resulting product was very tasty. I think the next time I try this I will use a lower temperature so that I can smoke them longer before they reach 160 degrees.
This is how they looked cut up and fried for breakfast.
