Here’s a graph with complete chronology of yesterday’s cook.
12:00 Started the cook with 85 original Kingsford lined up across the back and 20 lit new Kingsford at one end of the line. Guru powered with a 4 CFM Blower.
12:55 Tried to replace the blower with a 10 CFM unit and found the wires to be broken inside insulation.
1:35 Installed repaired 10 CFM Blower.
2:40 Removed water pan from grill over coals.
3:05 Peeked to look at coal status.
3:20 Added ¾ Weber chimney of lit new Kingsford.
4:45 Temps are dropping. Firing up the gasser.
4:55 Moved ribs to the gasser. Trying to maintain 250ºF for duration of cook.
7:25 Pulled ribs.
A few weeks ago, I tried a burn in the RK (no guru or meat) with the coals lined up much like they were yesterday and I ended up laying more across the top of the line which helped the temps up to the 240º range. I should have done that again yesterday but I tried to make this setup work. I’ll do that with Saturday’s cook of the remaining 2 slabs of loin backs and also start with ¾ Weber Chimney instead of just 20. I’ll also start with the 4 CFM blower as I think there was enough airflow, just not enough lit fuel. I’ll also put the water pan back on and see how it goes. I think I’ll have much better results this time.
All in all, I'm pretty happy with the way the ribs turned out but like I said earlier, I could have taken them off 30 or 45 minutes earlier.
