Good luck with that! Family are always the best guinea pigs for a new smoker. Your mods sound good. And the worst thing that happens is you have to eat "okay" smoked meat (which is still better than any other meat!).
I have never smoked cheese on a grill. I live in Florida so cold smoking here is not so easy without a freezer. I use a chest freezer that I installed racks in. How do you cold smoke on a grill like that??
Wow, those look great! I have never made a fatty, in fact, I had never even heard of such a thing. However, I am now very excited to make one. My arteries are getting hard just thinking about it. Thanks for the walk through, and the pics are great help!
