It is becoming harder to find pork tenderloins that are not packed in plastic, floating around in some kind of seasoned brine. I have nothing against brine, but those pre-seasoned tenderloins have an odd, artificial taste that becomes odder when smoked. Look for pork tenderloins in their natural state. From the cookbook, "Smokin" My Note: I found that after 25 minutes smoking, the meat was only half-done. My tenderloins were on the large side. I finished the tenderloins in my rotisserie for another 25 minutes, and they were perfect. Smoky juicy tender meat with a crispy outside. Used mesquite chips with the southwestern seasoning. Good combo.
