Got two pork butts in the old ECB right now. Hit the magical 140* at 4hrs. One was 141 and the other 145. Took a couple of readings to make sure and all is well. Using lava rocks in half of my water pan to help combat cold temps and some cardboard and a packing blanket. Inside temps about 260* using Apple and Capt Morgan as a spritz One picture is of the water pan and small lava rocks and the other is a prep just before they went on.Attachment 24131 Attachment 24132 More pictures to follow.
