I put a 7.5 pound butt and a 4-pound brisket on my smoker at 7 pm tonight. After 5 hours, I checked the temps and the brisket is at 190, but the butt is at 205. It's a horizontal smoker, and I put the brisket further from the heat source. Temp gauge read 225 at the cool end. Smoker is new (used twice), so I know the temp gauge is good. Checked the meat more than once and the temps are right. It's possible I guess that my thermometer is off, but the butt was falling apart so I'm sure it's pretty accurate. The bone was removed from the butt. The meat is resting now in a cooler. Has anyone else had a butt go so fast? Am I going to have a poor pork butt on my hands? It looks and smells beautiful.
