Dry the raw pork thoroughly and score the skin with a very sharp knife. Rub generously with salt and five spice powder making sure to season in the score lines.
Place in a windy area in your home and pat dry occasionally. Leave in the fridge overnight with the skin exposed to dry further. Alternatively, if you are in a hurry place the pork in a a fan forced oven on low heat (about 30 degrees) with the skin side up.
Take out the next day and let it warm up to room temperature making sure that the skin remains dry. Heat oven to 180 and place in lowest rack. Roasting time should be about 45 minutes for 1 kilo of pork. Lastly, turn the heat up to 200 and cook for another 15 minutes until the skin bubbles and turns golden.
