As said above. Don't turn the smoker on. Turning it on and leaving the door open won't work. It is going to keep the heating element on all the time. Just use your AMNPS and be patient. If it takes a couple of nigths no big deal.
I am pickling okra right now. So I already have gumbo on my mind. I guess I need to just freeze some okra instead of pickling it all. Your nephew is wise for his age. He knows good eaten! Happy smoken.David
