Preheat the barbecue for indirect cooking.
While the barbecue is preheating, take the pork out of the fridge.
Dry the skin of the pork and score the skin if the butcher hasn’t done this already.
Rub a little oil into the skin. Give the skin a good coating of salt.
Once the barbecue is preheated, turn the centre burner off and leave the outside burners on high.
Place the pork on the centre of the grill. Close the lid and leave the outside burner on high for 20 minutes to crackle the skin.
After the 20 minutes, turn the outside burners to medium and continue to cook the pork for a further 3/4 – 1 hour.
