Alright, so need some protips here. On Saturday I fired up the big green egg to smoke some wings. They turned out well, but I had a very hard time with temp management and consistency. In fact, I had to move the second batch into the oven for finishing because I had lost too much heat in the egg, and was unable to regain it. I'm under the impression that I must be doing something wrong, because I know this is supposed to be one of the strong points of a ceramic cooker when doing indirect cooking.
What I did:
1. Soaked the smoking wood for about 45 minutes.
2. Started the lump coal in a chimney. Waited until it was good an hot.
3. Put the hot coals in the cooker, followed almost immediately by the smoking wood.
4. Closed the egg, opened up the top and bottom vent.
5. Brought the egg to about 350 (target cook temp was at 325).
6. Started to try and get a consistent temp via vent control at 350.
7. I don't have the big green egg issued contraption for indirect cooking, so I used 4 bricks to give enough height for the second rack, and placed a drip pan with a little water inbetween the two racks. Closed the egg and attempted to maintain a steady temp before adding on the wings. Got it to about 330 and held it there for about 10 minutes. At this point the vents are maybe both halfway to 75% open.
8. Put the wings on. Opened the vents all the way and was only able to get the temp to 310. Never able to close the vents at that point. Was able to hold that temp for the about the 2 hours needed to cook the wings at that temp. Once I opened it to take the wings out, I was unable to regain any where near the 300 degree mark (around 225) and pretty much had to move the next batch into the oven to finish cooking after getting some smoke.
I will also say that the thing was not really smoking too well after about the 30 or 40 minute mark. So wtf am I doing wrong? I really want to do a long cook next Saturday (either pork shoulder or brisket), but am hesitant if I can't figure this out. Was considering a few problems, like maybe I just straight up don't have enough coal or fuel to maintain a burn for that long. The other thing I was thinking is that maybe the bricks I'm using provide too much mass, or are blocking the air flow of the egg so much that it isn't providing the coals with enough oxygen. I know that typically the vents are not opened more than a little bit to control the temp, but if I did this, I feel like the temp would drop drastically and may not even maintain a fire. I live at elevation, so I figured it would require a little more oxygen, but having the vents pretty much wide open the whole time to maintain a good temperature seems crazy. TIA for any input, I definitely appreciate it, and I need help.
