I’ve read about using an ice tray to keep inside the grill cool for smoking the cheese. I’ve never done that myself, as here in Phoenix, it’s in the 80-90 at night, and you know where during the day. I did mine after dark in the winter yet here. I think it was 60 out. Your just suppose to keep where your smoking area temp below 90 if I remember. I put my cheese on a wire rack on top shelf, smoking tube on bottom. Cheese way to the right, smoking tube all the way to the left. I used a whole tube and flipped the cheese half way through.
