Step 1
Take the wrapping off the pork and leave it in the fridge for a day or two to dry out the skin.
Step 2
Take it our of the fridge and let it come to room temperature for about an hour, which will help it cook evenly.
Step 3
Pre-heat your oven to 230 deg C for at least 20 minutes so it’s nice and hot. Rub the skin with olive oil and salt. Plenty of oil and plenty of salt!!
Step 4
Pop the pork into the oven and let it cook at that high temperature for 20-30 minutes, until the crackling starts to form, then turn the temperature down to 165 to 175 deg C and keep cooking.
Step 5
Cook it until it gets to an internal temperature of 68 to 72 deg C and then let it rest.
If the skin hasn’t crackled you can put the pork under the griller, but be careful as it’ll crackle up very quickly!
