Got this at local meat market.
Almost 15#. There was two in the package. I took one out and cut it in half. One 4# the other 3.75#
Put some rub on and wrapped up in fridge over night
After 4 hours at MES set at 275. Probe read 255. IT was 177.
2 hours later IT hit 181 and started to go up more quickly. Reduced MES temp to 250 and waited 3 more hours for IT to hit 205
Wrapped in foil and put in cooler stuffed on top with hand towels. Let rest 2 hours.
Here is the final result from one. Super moist and juicy with good bark? I think.
Btw, smoked with AMZN with hickory pellets for 5 hours.
