pork Shoulder
Pork Shoulder
The pig's front leg and shoulder, sold as two pieces: the Boston butt on top and the picnic below it, running into the shank. The shoulder holds the animal up and works all day, so it's dense with connective tissue — which is exactly why it's cheap, and why it falls into shreds given enough time.

Nowhere near the pig's rear end, whatever the butcher called it.

You're feeding a crowd, you have all day, and you want leftovers.
The butt is not the butt. It sits at the top of the front shoulder, about as far from the pig's hindquarters as you can get. In colonial New England, butchers packed cheap shoulder cuts into barrels called butts for storage and shipping; the container's name migrated to the meat and never left. Boston got attached because that's where the trade was centered.
Collagen is the whole story. A muscle that works constantly is strapped with connective tissue, and connective tissue is tougher than muscle fiber at every temperature you'd cook a steak to. Held above roughly 160°F, it starts converting to gelatin — slowly, over hours. That single fact explains the whole cut: a shoulder at 175°F is dry and chewy, and the same shoulder at 200°F pulls apart with a fork. It isn't done when it's safe. It's done when it's rendered.
Butt or picnic. The butt is the easier animal: evenly marbled, no skin, and it shreds cleanly. The picnic is cheaper, tapers into more sinew and bone, and comes skin-on, which is either a bonus or a chore depending on whether you want crackling. When a recipe just says "pork shoulder," either one works.
You're buying time, not tenderness. This stays the cheapest large cut on the pig precisely because it costs most of a day to make good. Nothing about it rewards hurrying, and no amount of money buys a shortcut.

| Cook to | 195–205°F, judged by feel more than by number — a probe should slide in with no resistance. Safe at 145°F, but at 145°F it's a tough roast. |
Trim the fat cap to about a quarter inch, season heavily, and cook it low — 225–275°F, smoker or oven, it makes less difference than people claim. The cut is far more forgiving of temperature than of impatience.
Bone-in is worth choosing when you have it. The blade bone pulls clean out when the shoulder is genuinely ready, which is a better doneness test than any thermometer.
Rest it a full thirty minutes, still wrapped, before you touch it. Pulling straight off the heat throws out steam that would otherwise settle back into the meat.
For carnitas or anything browned, cut it into fist-sized chunks first — more surface, more crust, and a third of the time.

Brisket
The beef equivalent for a long smoke — same low heat, same all-day patience — but it carves into slices rather than pulling apart.
Common questions
How long does a shoulder actually take?
Roughly an hour and a half to two hours per pound at 250°F, so twelve to sixteen hours for an eight-pounder — but weight predicts this badly, and you should cook to feel rather than to the clock. Expect it to stall somewhere around 150–170°F and sit there for hours: that's evaporative cooling, the meat sweating as fast as the heat goes in. It isn't stuck and nothing is wrong.
Should I wrap it?
It's a trade. Foil or butcher paper pushes through the stall and can save two or three hours, but it also steams the surface and softens the bark you spent all morning building. Paper breathes and costs you less crust than foil. If you're not against the clock, don't wrap at all.
Can you overcook a pork shoulder?
Yes, despite its reputation. Past about 210°F the muscle fibers give up completely and the texture turns from shredded to mushy and vaguely pot-roasty. The window is wide — far wider than a chop's — but it does have a far edge.
Do I need to leave the fat cap on?
Trim it to about a quarter inch. A thick cap doesn't baste anything: rendered fat runs off the outside, it doesn't travel into the muscle. What it actually does is block smoke and keep your rub off the meat.
