Preheat oven to gas mark 8 (220°C / 425°F).

Score the fat on top of the leg of pork, creating a zigzag pattern without cutting into the meat.

Rub salt into the scored fat.

Place the pork in the middle of the preheated oven, covered with a lid or foil.

After 20-30 minutes, reduce the oven temperature to gas mark 4 (160°C / 320°F).

Cook the pork for 20 minutes per pound plus an additional 20 minutes.

Check that the juices run clear when the pork is cooked.

Let the pork cool on a meat tray or plate.

After 20 minutes, gently slice the crackling off.

Reserve the meat juices for gravy.

Slice the pork and serve with roast potatoes, vegetables, gravy, and apple sauce.
