Looking for some suggestions and tips for my next pulled pork attempt. I am using a Smoke Hollow electric smoker. I put on a 9 pound butt last night at 240 degrees. It was maintaining a temp of 215-225. I left it on the smoker for 14 1/2 hours until internal temp was at 185. I pulled it off and wrapped it in foil and placed in a cooler for about 90 minutes. After letting it rest for the 90 minutes, I opened it up to start to pull. I found that the meat was still juicy, but it was not very tender. I had a harder time than normal pulling the bone out. It still tasted good, but it wasnt as tender as it has been in the past. I am not sure why, because I did it the same was as I have in the past with no issues. Any help with what might have been the issue on this so that I dont have this problem next time. Thank you in advance..
