<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> Its now 2 am and 15 hours into the cook. The ET-73 went off at 1am when the temp dropped to 198. Checked and almost all the charcoal was gone. At least now I know how long a full ring lasts in bad weather. Filled the ring with unlit and added 30 lit, also added water. Did all this right through the door.
Around 8pm the meat was at 166 but has since dropped back down to 151 so I dont know how big a problem this may be.
<HR></BLOCKQUOTE> Good man Jim! I find it hard to get up middle of the night sometimes. Good On Ya for doing all this through the access door too. That's dedication! I think you're still tracking well, should be to 195F by noon. I kinda like 200F+ for butts myself currently but anything over 190F should work for ya.
I have one concern though, ash build up. You are now on your second ring and after a time there won't be anywhere for ashes to go cuz the bottom will be full and the bottom briqs will constantly be smothered by the ash. You could have taken a little bigger hit temp wise, disassembled to scoop some ash out into your trusty galvanized can, then reassembled to alleviate this concern later on. However, I probably would have done exactly as you did.
Two things to watch for: ash clogging bottom vents & temp dropping cuz some coals are being smothered. For the first issue, keep ash build up away from vents by moving it away from vents insde with tongs. For the second issue you may have to stir/sift through coals several times towards the end. If it gets to be a problem try to scoot the ash to one side of the ring and pile all the remaining briqs to the other side.
As for recovery to previous temp, I don't find it to be a big deal. Hard to describe ... it's kinda like this .... it takes time and heat to do the 'work' to get to where you were ... after a drop the work is already done so it takes much less time and heat to get back to previous temp. Once you're back to previous temp the normal progression resumes.
You lost 15 degrees on the meat temp but I would be suprised if it takes more than a couple of hours to exceed your previous temp at the 247F pit temp you reported.
The amount of meat you are doing and your weather conditions are making this a biathalon cook. Keep up the great work!
