I always cook my pork in a pan. At the end of the cook, the pan looks most unappetising - a sticky burnt mess.
But then I put the pan on a very low heat, and deglaze the pan with cider vinegar. All that sticky mess turns into wonderful gravy, which I then thicken with mustard powder before adding back into the pulled pork.
Worth every effort.
Note: I don't bother cooking *over* a pan, my pork goes *in* the pan. It makes it easy to take out of the smoker when cooked, and it still seems to get plenty of smoke.
