Pork Shoulder

A front leg never stops working. It holds the animal up, absorbs every step and gets no rest, so it builds connective tissue and lays fat down through the muscle rather than in one clean cap. That is the character of this whole end of the pig: not tender, but generous, and very hard to overcook.

Butt and picnic are the two halves, and the naming is the confusing part. A whole front leg is split at the joint. The upper half is the butt — the blade bone runs through it, the fat is spread evenly, and it is the piece behind essentially every pulled-pork recipe, typically six to ten pounds bone-in. The lower half is the picnic: arm and hock, skin on, more seams and more sinew, usually a little cheaper per pound and with less usable meat once trimmed. The rear of the pig is the leg, on its own page. Nothing here is anywhere near it.

Doneness is a texture, not the temperature you were taught. Safe happened long before you are finished. What you are waiting for is collagen converting to gelatin, which takes hours somewhere past 160°F. Pulled pork lands between about 195°F and 205°F, and the gap between 180°F and 200°F is the whole difference between slicing it and shredding it.

The stall is real and it is not your cooker. Somewhere around 150–170°F a big roast stops climbing and can sit flat for hours. Moisture evaporating off the surface is cooling the meat about as fast as the cooker heats it. Wrapping tightly in foil stops it; so does waiting, and the bark is better if you wait. Nothing is broken.

The Iberico cuts here are the exception to every sentence above. Presa is the collar muscle, secreto is a thin marbled sheet hidden under the back fat, and pluma is the tapering tip where the loin runs into the shoulder. Their fat is high in oleic acid, so it is soft and renders quickly instead of needing hours to give anything up. These are cooked like steak, hot and fast, to 145°F. Braising them wastes the marbling and the money at the same time.
