I have had a New Braunfels smoker for some time now. I get great results with Boston Butts. Should I not cook with just wood on this thing or what am I doing wrong. Sometimes meat comes out too smokey and sometimes bitter. Are these not meant to cook with just wood? Maybe I should cook with charcoal and just add a little wood for flavor. I wonder all the time how people cook with just wood but don't get an overbearing smoke flavor.
