My day has not gone quite as I planned...my 4 Boston butts have been on the egg since about 2:30 this afternoon. I had to breakout a new dome thermometer for the cook and I am not sure it is reading correctly. I calibrated the thermometer in boiling water prior to the cook. I settled the egg at about 250 for about 20 minutes, then I put on about 30 lbs of butt and the dome temperature dropped, as expected to about 100 degrees.
As I mentioned in an earlier post today, I had my daughters high school graduation tonight. When we left for the graduation ceremony at about 4:00 the dome was only about 110.
I got back home at about 11:15 tonight...dome temp read only 150....I put a thermometer in each of the butts....all of them read between 158 & 162.
I have no idea if I have a bad thermometer???or if the dome temp ever reached 250 again??? is theis trash???HELP
