1.Untie pork and using a sharp knife, score skin at 1cm intervals. Place pork skin-side up on a rack in the sink. Pour over boiling water. Drain then pat dry with paper towel and lay skin-side up in a roasting pan. Chill uncovered overnight. (This will dry out the skin for perfect crackling.)
2.Place apricots in a bowl and cover with boiling water. Leave for 15 minutes to soften. Meanwhile, heat half the oil in a frying pan over medium heat. Add onion and bacon, and cook for 8 minutes or until onion is softened. Cool completely. Process bread in a food processor to form crumbs. Transfer to a bowl and stir in apricots, onion mixture, apple and parsley. Season with salt and pepper, and stir to combine.
3.Preheat oven to 220°C. Lay pork, skin-side down, on a chopping board. Spoon filling down the centre of the pork, then roll firmly and tie securely with kitchen twine.
4.Rub skin with oil and sprinkle generously with salt. Place pork onto a rack in a roasting pan. Roast for 30 minutes. Reduce heat to 190°C and cook for a further 1 hour and 30 minutes (allow 45 minutes per kilo) or until cooked through. Transfer pork to a large plate.
