I got a nice $1.49/lb deal on some pork loin roasts that are actually two pieces together in elastic netting. I plan to smoke them, but this will be the first time with the nets still on. The label instructions call for roasting at 375F and they say nothing about removing the netting first so I assume it's good to 375 at least, and the smoker won't get that hot, so they should be OK. But, no one cooks direct over coals with them still on, right? How hot can you safely get that elastic material?
