Had them in the smoker for almost 5 hours and they never got hot enough to sweat any grease out. Didn't surprise me at one degree above zero. They at least got 5 hours of non stop solid thick rolling smoke from the big pile of cherry branches. I took them out and popped in the kitchen oven set at 225 degrees. After 18 min the internal temp was just under 190 degrees. Took the sticks out and wiped off all the grease that sweated out and threw them in zip lock bags and into the fridge.
