Kalua Pig

Ingredients

• 1 (approx. 45–55 kg) whole pig, cleaned and dressed
• 500 g Hawaiian sea salt (alaea or unrefined), for generous rubbing of the cavity and skin
• 20–30 large banana leaves, wilted over an open flame until pliable; fresh stiff leaves must not be used
• 4–6 lengths wet burlap sacking, soaked thoroughly in water before use
• enough to fill pit lava rock (basalt), volcanic rock only — sedimentary or limestone rocks must never be substituted
• Contemporary oven adaptation
• 2–2.5 kg bone-in pork shoulder, scored deeply all over
• 30 g Hawaiian sea salt, rubbed generously into scores and surface
• 1 tbsp liquid smoke, splashed over the salted meat
• 4–6 large banana leaves, wilted over flame until pliable; available frozen at Asian grocery stores
• as needed aluminium foil, for a tight outer wrap over the banana leaves

Method

1. 1
   Dig a pit deep enough to contain the dressed pig with a minimum of 30 cm of earth cover above it. A shallow pit loses heat rapidly and produces uneven cooking. Fill the base with lava-rock basalt and build a hardwood fire over the stones. Burn the fire for 3–4 hours until every stone glows bright red. Stones that are merely warm cannot sustain the internal temperature required for the full cook — the visual test is an even, unwavering red heat across all stones.
2. 2
   While the stones heat, wilt the banana leaves by passing each one over an open flame. The leaf is ready when it turns a darker, translucent green and becomes fully supple in the hand — a stiff leaf tears during wrapping and breaks the steam seal. Set the wilted leaves aside in a stack.
3. 3
   Rub the pig generously inside the cavity and across all exterior surfaces with Hawaiian sea salt. The mineral character of the salt is part of the dish's flavour identity; fine table salt cannot replicate it.
4. 4
   This is where the dish lives or dies. When the stones have reached bright-red heat, clear any unburned wood and arrange the stones as an even bed. Lay wilted banana leaves over the stones in a thick, overlapping layer. Place the salted pig on the leaf bed, then wrap the pig entirely in further banana leaves, sealing the aromatic steam inside. Cover completely with the soaked wet burlap. Shovel the excavated earth back over the mound to a depth of at least 30 cm, sealing all edges. Do not open the imu for a minimum of 6 hours — every opening releases accumulated steam and extends the total cooking time significantly. The earth seal must be complete and unbroken: no visible steam escaping from the mound.
5. 5
   After 6–8 hours for a medium pig (10–12 hours for a large animal), unearth carefully and open the banana-leaf wrapping. The internal temperature throughout the deepest part of the shoulder and haunch must read 85°C or above. The definitive test beyond temperature is that the meat yields and pulls cleanly from the bone with no resistance.
6. 6
   Transfer the pig to a shredding surface. Kalua Pig is always shredded, never sliced. Pull the meat apart with two forks or by hand — the fork-tender flesh separates naturally into long fibres. Distribute the rendered fat evenly through the shredded mass as you work. The finished pile should be moist, smoky in aroma, and uniformly seasoned throughout.
7. 7
   Contemporary oven adaptation: Score a bone-in pork shoulder deeply, rub with Hawaiian sea salt, and splash with liquid smoke. Wrap tightly in wilted banana leaves, then enclose the entire package in a double layer of aluminium foil with no gaps. Cook at 140°C for 8 hours. The foil package is unwrapped at the table. The meat is done when it pulls from the bone without resistance and the internal temperature exceeds 85°C throughout.
