I am building a new UDS and I am wondering what I should use to fuel my smoker charcoal or lump wood? I have cooked on a Big Green Egg before so I am use to using lump wood but I have never cooked with charcoal before. What do you guys suggest I use on my UDS? I was thinking about using both charcoal and lump wood mixed in my basket along with my wood chips. What do you guys suggest I use?
