I'm wanting to do some smoked venison sausage as I've never smoked it before, only stuffed, froze it, then cooked on the grill. What is the trick to get the low temp in a masterbuilt xl? Need to go from about 125-165* according to the recipe I want to try. I'm assuming I could put charcoal in the pan and just try to regulate temp that way. I'd like something much easier to do though! Thanks.
