The stall isn't stuck. It's sweating.

Sometime around hour three on Saturday, your thermometer is going to stop moving — and stay stopped long enough to make you question the fire, the meat, and several of your life choices.

Published by The Weekend Pit · Every temperature verified against USDA guidance and cross-checked against at least two credible sources — all named at the bottom of this page.

The short answer

A stall is evaporative cooling, not a broken fire. Around 150°F internal, moisture pushed to the surface of the meat evaporates fast enough that the cooling exactly cancels the heat of your pit, and the temperature flatlines — sometimes for hours.

Three honest ways through: ride it out for the best bark, wrap at 150–160°F to stop the evaporation, or run the pit hotter. Pick one before you light the fire.

The Deep Smoke

Why the stall happens — and three honest ways through it

The why. Big cuts climb steadily to about 150°F internal, then flatline — sometimes for hours — before climbing again. For decades pitmasters blamed melting fat or dissolving collagen. Then physicist Greg Blonder actually tested it, and the answer turned out to be the same reason you don't overheat on a July run: evaporative cooling. Around 150°F, moisture pushed to the surface of the meat starts evaporating fast enough that the cooling exactly cancels the heat of your pit. Your pork butt is sweating. In Blonder's test rig the standoff held for about six hours before the surface dried out and the temperature moved again. Nothing is wrong. Nothing is broken. It's physics, holding the door.

Ride it out

Dry surface eventually wins. Deepest bark, longest cook, zero effort. The price is time you have to build in up front — pitmasters pad the schedule with buffer hours and let a long rest absorb the extra. Choose this when dinner is flexible.

Wrap it — the Texas crutch

Somewhere in the 150–160°F range, wrap the meat tight. No evaporation, no cooling, no stall. Foil is the full crutch: it braises the meat in its own juices, fastest through the stall, softest bark. Butcher paper is the compromise — it breathes a little, so it's slower than foil but kinder to bark. For pulled pork, use foil without guilt: the bark gets mixed in when you pull it anyway. Save the paper debate for brisket, where bark is the trophy.

Run hotter

The stall shrinks as pit temperature climbs, and approaching 300°F it can disappear entirely. Legitimate technique — but it trades away some of the low-and-slow margin for error, so it's the advanced lane, not the Saturday default.

The one mistake everyone makes: deciding mid-stall. It's 2pm, the butt has read 157°F for two hours, guests land at six, and panic starts negotiating — crank the pit, pull it early, google furiously with rib-rub thumbs. Every bad outcome starts there. The fix costs nothing: pick your stall plan before you light the fire.

“It's not stuck — it's sweating. Wrap it and it can't sweat; wait it out and the bark's better.”

This Weekend's Cook

Pulled pork for a crowd — and a front-row seat to the stall

A bone-in pork butt is the best teacher in barbecue: cheap, forgiving, and it stalls just like a brisket without a brisket's consequences.

Backward from Saturday 6:00pm dinner
When	What
Thursday	Buy an 8-lb bone-in pork butt (shoulder). While you're out: heavy-duty foil.
Friday, 8pm	Trim the hard fat cap to ~¼". Salt and rub all over. Fridge, uncovered, overnight.
Saturday, 4:15am	Light the pit. Coffee.
4:45am	Butt on, fat side down. Pit at 250°F and hold it there.
~8:00am	Internal hits ~150°F. The stall begins. You, unlike everyone else, smile.
At 160°F internal	Wrap tight in two layers of foil, back on the pit.
~3:30–4:30pm	Start probing. Pull at 195–205°F internal, when the probe slides in everywhere like warm butter and the bone wiggles free.
Off the pit	Rest, still wrapped, in a dry cooler with towels — 1 hour minimum. Finishes early? That cooler hold keeps it hot for 3–4 hours, which is why this timeline can't really fail.
6:00pm	Pull it, season the pile with a pinch more rub, serve.

You'll need

The butt, kosher salt, a simple rub (¼ cup coarse black pepper, 2 tbsp paprika, 1 tbsp garlic powder, 1 tbsp brown sugar — salt separately and generously), foil, a probe or instant-read thermometer, buns if you're civilized about it.

The rig

The numbers above assume a pellet grill or any smoker that holds 250°F. On a kettle, set up two-zone with a full chimney plus 3–4 wood chunks, and plan to feed the fire roughly hourly — the butt doesn't care what it's cooked on, only that the pit holds steady.

The numbers

Pit 250°F · wrap at 160°F internal · pull at 195–205°F internal · rest 1hr+ wrapped.

USDA's safety floor for whole-cut pork is 145°F + 3-minute rest — you'll blow past it by lunch. Tenderness is the reason for the rest of the climb.

Pit Find

ThermoWorks ThermoPop 2 — $39

Everything in this issue assumes you can actually read the meat's mind, and the reviewer consensus for doing that on a budget is the ThermoPop 2: 2–3 second reads, ±1°F by ThermoWorks' own spec, and a backlit screen that flips to stay readable in either hand — including at the 4:45am light.

The flaw, because there's always a flaw: the little probe cap is practically engineered to disappear into a junk drawer, and it's a beat slower than the Thermapen ONE ($74 on sale as we wrote this, usually ~$115) — the buy-once version for the cook who already knows this hobby is permanent. Start with the $39 one.
