It seems that every time I cook pork butts, the end product has been edible but far less than what I have expected. A lot of the meat has turned out "mushy." I prefer pulled pork, so I usually let them go to the 190 range then rest for 30 minutes. On only one occasion have I gotten the results that I wanted, and I can't seem to duplicate this cook. I have injected with FAB a couple of times but that only made it worse. Any suggestions?
