I started this butt late, around 1pm, it a 5lb and I did my first injection. I did not wrap it so it took a while to reach an internal temperature of 203 at a smoking temp of 225 on my smoker. I pulled it off at 10:30pm because I was starving.. When I went to shred it, it looked like the fat did not render down or melt away, did I do something wrong or should I of let it cook longer since I injected it?? Any advice is welcome!!
