You might just beable to poke at the coals to let ash fall to let lower coals light up. I did my first port butt this weekend also. filled up the charcoal ring to the max with wood on top and check to see if the water pan would hit. Then got 20 coals off the top and lit them around 10pm. Put the meat on a little before 11pm. That was all i needed for the entire 15hrs it took to cook the butt. I did have to poke at the coals to let ash fall a few time but didnt have to add more coal. Matter of fact when i took the meat off the temp inside was 260* (opened the vents so it can finish faster) My regular temp was between 225-245 .Originally posted by Mike Batsarisakis:
You did the right thing by adding coals at the 6 hour mark.
