I found a lamb roast in the freezer that's rolled and tied into a perfect three inch diameter tube that's filled with stuffing. it has a good thin layer of fat around the entire outside. The stuffing is about 1.5 inches and runs right down the centre of the roast. My guess is that after it defrosts I can push out the stuffing, leaving a perfect hole for a thick wooden skewer, and spit roast it over a fire. My question is really about the skewer. If the roast were in the oven, it would take over an hour to finish cooking. Would a thick piece of green wood last that long over a fire before drying out and bursting into flames?? Would you shave the bark off to keep it reasonably clean, and would that also make it more flammable? My sense is that it would. Perhaps I could simply shave the bark off the part that touches the meat. Does anyone else spit-roast meat like this??
