History
Kalua means 'to bake in an underground oven' in Hawaiian. The traditional imu method dates to pre-contact Polynesia: dig a pit, line with kiawe wood embers and lava stones, wrap a whole hog in ti and banana leaves, cover with damp burlap and earth, leave 8 to 12 hours. The dish was the centerpiece of luaus before and after Western contact. The Toguchi family's Highway Inn has served kalua pork plates since the 1947 Waipahu opening, now with a 2013 Kakaako outpost; Helena's Hawaiian Food on North School Street has cooked the imu since 1946.

Yield Serves 6 to 8Hands-on 20 minTotal 8 hr 30 minDifficulty Intermediate
Ingredients
- 2.5kg bone-in pork shoulder (Boston butt)
- 3 tablespoons Hawaiian alaea sea salt (or coarse pink salt)
- 1 tablespoon liquid smoke (mesquite or kiawe)
- 8 fresh ti leaves or 6 large banana leaves (or substitute with parchment plus foil)
- 240ml water
Method
- Pat the pork shoulder dry. Score the fat cap in a 2cm diamond pattern. Rub with the Hawaiian salt all over.
- Drizzle the liquid smoke across the fatty side and rub in. This is the chef's shortcut for imu smoke without the pit.
- Lay ti or banana leaves on a heavy roasting tray in a cross. Set the pork in the centre. Pour 240ml water around the meat.
- Wrap the leaves over the pork, sealing the top. Cover the whole tray tightly with foil, then a second layer.
- Roast at 150C (300F) for 8 hours. The meat should pull apart with a fork; if not, give it another 60 minutes.
- Rest 20 minutes still wrapped. Unwrap, shred with two forks. Toss with any pan juices and a final pinch of Hawaiian salt.
Tip from the editors. If you have a smoker, replace the liquid smoke with 2 hours of kiawe or mesquite smoke at 110C before the foil-roasting step. Result is closer to imu.
