Hey, I just got a Mastbuilt electric smoker today. I am responsible for making a 10lb pork loin next weekend for our family Christmas. I was wondering if I need to do anything to season my smoker before using it for the 1st time? Also, I would be open to any suggestions for rubs, or marinades as well... I would consider myself a great griller, but I am excited to start smoking meat. I am just nervous that I have to grill for Christmas on my 1st smoking experience. Thanks ahead for any and all advice!
