I recently purchased a Brinkmann Smoke'n Pit horizontal smoker ($200 variety) with an offset firebox. This is my first smoker and I have no past experience smoking meat. I broke it in yesterday on a small pork butt and a slab of spare ribs. For fuel I used aged hedge (osage orange) and kingsford charcoal. I also used soaked hickory chips for flavor. The meat came out tasting good but I'm sure I could use some tips as I was basically winging it. I'm not sure if I should be using this wood for fuel in this type of smoker. Also is it alright to use hedge wood for fuel? On a couple of occasions I had thick white smoke coming from the stack. I thought this was good but after doing some reading, maybe it's not?? I have plentify black walnut and hedge available. Other than that I would need to purchase it. So, any tips on the fuel for smokeing with this type of smoker would be great. Also, what should the smoke look like while smoking (white, blue, black, clear)?? Thanks.
