Brisket update (dome/grill temp results)

DavidR

Ok, 5 hours into the cook. I just opened and verified with an instant read thermometer that the meat probe is accurately reading the correct temp. It's about 155 internal throughout, point and flat. I moved the potato to behind the brisket on the grid, except this time, it's over the drip pan, and it now reads the same as the top probe. So, therefore, I'm regarding the top probe as the cooking temp.[p]Latest readings:[p]Dome - 280
Bottom - 176
Top - 225
Potato - 220
Internal - 154[p]When the internal reaches 160, it'll be decision time. Either leave it until it reaches a temp of 185 . . . or . . . . wrap it foil with a couple of bottles of Stubb's Moppin Sauce poured in, and let go to 185 that way. [p]This is fun. A little anal retentive maybe, but it's fun.;)

DavidR,
Interesting, did you notice what the potato temp. was before moving it????
It was tracking the dome temp. pretty well and I was wondering if it still was.
Thanks, we will be waiting to see what you do or don't do with the foil.

New Bob,[p]When I lifted the lid, I noticed that the probe tip was very close (about a half inch) to the side of the dome, and right above the opening of the setter. The potato and the dome probe were right in line with each other, and in the path of the updraft coming directly from the coals. They were practically reading the same temps. [p]Now, I don't want to stir up a hornet's nest here, but from what I have observed, the use of a plate setter will deflect the direct heat away from the meat on the grid, but it appears that it does NOT deflect the direct heat from the dome probe, which would explain the big variation in temperature.[p]

DavidR,
At least we know that the dome is is not that far off on the general air temp.
Now, yesterday when I ran the dry temp. my probe was in the center of the grill (over a setter) and also tracked the dome pretty close, interesting why a hunk of meat (except for being a heat sink) would cause such a difference???? Could it be that it's just the meat sucking in the heat causing the lower reading?????
Things to think about,
Sounds like you're having a good time.

DavidR,[p]I think others that have actually investigated this will agree with your last paragraph. It is good to see you take the time to really see what is going on.[p]Ashley

New Bob,[p]I decided to foil the brisket. It's back on the egg now, plate setter is still there. Drip pan taken out. The potato is sitting on the grid above one of the legs of the setter.[p]Dome - 280
Potato - 225
internal - 160
