Build the hardwood fire in a separate burn barrel, using oak or hickory logs. Allow the logs to burn fully down to glowing coals — no flames, no unburned wood. This takes 1–2 hours and must be running before the hog goes on the pit. The coals are ready when they glow orange and hold steady heat without active combustion.

Lay the butterflied hog meat-side down on the pit grate or steel rods over the prepared coal bed. The pit temperature holds at 107–120°C. Shovel a heavier concentration of coals under the shoulders and hams — the thick sections — and fewer coals under the ribs and belly, which are thin and will cook faster. The skin faces upward, protecting the meat from drying throughout the main cook.

Manage the coals continuously throughout the cook. Every 30–45 minutes, shovel fresh coals from the burn barrel and reposition them under the hog: more under the shoulders and hams as needed, less under the belly. The discipline of the whole hog is that every section of the same animal demands individual, simultaneous attention — this is where the dish lives or dies. The cook runs 12–18 hours.

After 12–17 hours, test the thick sections. The shoulders and hams should yield easily to a probe or the back of a heavy spoon — the meat pulls away from the bone without resistance. The skin remains pale and pliable at this stage.

In the final hour, flip the hog skin-side down directly over the coals. Monitor the skin constantly. It will blister, contract, and colour deeply. The crackling is done when it is rigid, blistered, and sounds hollow when tapped.

Remove the hog from the pit. Using a cleaver, chop through the meat, skin, and rendered fat together directly on the pit or a heavy chopping surface. The chop is rough and irregular — not sliced, not pulled. Every portion should contain crispy skin fragments, tender meat, and rendered fat in the same rough mass.

Combine the vinegar, salt, black pepper, and red pepper flakes. Dress the chopped meat with the sauce at the moment of service — not during the cook. The sauce is a seasoning: it must cut the pork's richness without masking it. Taste and confirm the sharp, thin, acidic character is present and immediate.
