This is my first smoke, with my new MES. I put my butt (5 1/2 pounds) on about 7:30am. Set the temp to 225 (MES temp). It's been on for about 3 hours - but my Digital probe temp only shows 196 (the MES shows 225). I've read don't trust the MES temp, but should I increase the temp on the MES to get my prob to read roughly 225? Or what should I shoot for on the temp? Any help would be appreciated. Also, I rubbed with Mustard and a dry rub last night and am using part apple juice/water in the water bowl. How long will this take until it's complete? Should I take it out and foil it at 160 or keep it in until the meat prob shows 200. Foil or no foil?
