How long shoud I smoke it to get it to 156? The instructions in the box says 120 for 1hr. w/no smoke, then to 160 for 30 min w/smoke on. Then 180 until sausage reaches 156, leave somke on gor 2 hrs. ASs it sits they have been on for about 1.5 hrs and are currently at 142 with MES set with what the instructions called for. Does that seem pretty quick to get up to that temp or not?
