Those were rubbed all over with yellow mustard and then rubbed with Durkee Grill Creations Chicken and Rib rub. They have no sauce on them at all. I prefer no sauce. I was shooting for noon but they didn't get to 190 deg until 1:30. My remote thermometer woke me up at 1:30 last night saying the grill was colder than the set value. My batteries were dead and I had to go to Walmart to buy batteries at around 2am. The last two hours the butts were wrapped tightly in foil so we could pick them up when they were done.
Man they were perefect!!! Wish I could share, the freezer is fuller now. BTW we used Apple for smoke. The grill was made by my son, it used charcoal in one side and I put a propane burner in the other. We start with charcoal and the soaked wood that is wrapped in foil with a couple of small holes poked it it. After a couple of hours the charcoal beging to burn down and then we go to propane and set it and forget it "unless the thermometer needs something"
