Wife asked me to do a pork shoulder we had in the fridge at about 10am today so I decided to try my hand at a hot and fast cook which is something I've been meaning to try. Pulled out the shoulder and rubbed it, then fired up some B&B lump oak to put over some apple wood chunks and see how well I could do this on my kettle. Ran the sucker at 330f for 5 hours, pulled when internal hit 194f and wrapped in foil and a towel to rest for an hour before pulling. The results were killer and for large pieces of meat I don't feel like low and slow is the only way to go.
I'm hearing you hooligan, i used to sit next to the smoker religiously the entire cook, maintaining 225 no matter what. Until i was camping one time and had to put a pork on in a hurry. I knew the temp was 300+ but i needed to get it done. I shut the lid and forgot about it. Returned that night to one of the juciest pork i'd ever pulled... made me wonder why i'd bothered fussing over 40degrees all those times...
There is no right or wrong way to bbq, but that goes contrary to how I do it.
I will smoke things hot (275 and above) for things that don't have a lot of mass like ribs, or meats that don't have a lot of collagen like pork loin, chicken, and turkey that I'm really just trying to infuse with smoke flavor.
For bigger pieces of meat like brisket and shoulder, I go low (250 and under). The reason being even at a high temp, it's still going to take a while to get the center of the clod up to the target temp. The closer the temperature of the smoker is to the target, the less likely it is to overcook it. If I want the internal temperature of the shoulder to be 195, and I'm smoking at 300, the exterior portion is going to be way above that before the interior is done.
At the end of the day though, the goal is to make something delicious, and if you get that the way you're doing it, good on you .
