Pink Himalayan / Rock / Sea Salt
Preheat a deep roasting tray in the oven at 200°C for 10-15 minutes.
Lay the sheet in the tray, skin side down. Sprinkle salt over the fat side.
Roast for 30-40 minutes in the middle of the oven. The skin will begin to curl.
Remove from the oven, turn the skin over and uncurl it as much as possible. The skin should be fairly flexible still.
Roast for at least another 45-60 minutes. Depending on the thickness of the skin, you may want to remove any liquid fat from the tray to prevent it from smoking.
Ensure the tray you drain the fat into is capable of holding extreme heat. Once cooled, store this fat in the fridge and use as your own homemade lard :)
