Good morning everyone, it's a great day to smoke some butt this morning here in Cincinnati. I recently acquired a used Traeger Junior smoker and have been playing with it some but I'm not at all comfortable with it. I've smoked some chicken thighs, cheese and some Jalapeno Poppers with acceptable results. In addition to the Traeger, I have an iGrill2, 4 probe thermometer and the difference between the Traeger grill temp and the iGrill temp is up to a 50 degree difference at times. The Traeger reports lower than the iGrill. I have cleaned the Trager probe and ensured it's not touching the grill and I've positioned one of my iGrill probes near the Traeger probe propped off the grate about 1.5 inches. I also have probe #2 in the center of the pork. This morning at 7 a.m. I fired up the Traeger by setting it on Smoke and let it set for 10-12 minutes. Once the smoke was rolling I turned it up to 180 degrees. The temp shot up to 310 degrees according to the iGrill probe and 280 on the Traeger. The temp slowly dropped to about 225 (iGrill) or 195 (Traeger) at about 7:20. It's now 9:38 and I've had a steady "sawtooth" pattern according to the iGrill. It's been as high as 288 and as low as about 180 according to the iGrill chart. I'm just afraid of ruining this beautiful 8.5 Boston Butt I have on the grill. The meat started out at about 35 degrees this morning and is currently at 68 degrees internal temperature. I started this post at about 9:30 and it's now 11:00 a.m. despite all the temperature fluctuations I think the meat temperature looks good. I started at 35 degrees and after 4 hours I'm at 104. I'm attempting to post a screen shot of my iGrill temp charts. I hope you can see it. Please let me know what you think. Do you think the meat will be as awesome as I envisioned when I started? Thanks for any comments or suggestions you may have.
