I have smoked potatoes (parboiled first) several times and am having issues gettin them done. The first time they were in with the meat at 240F for 3hours and were soft and tasty. I did them at a lower temperature and they were hard so realized temp an issue. The last time I smoked them at 240F for 3+ hours and they still needed time in the microwave to soften up. Any clues what else affects them. I place them above the meat to avoid drippings and, well, heat rises.
