Before cooking: Preheat oven. Put 2-4 tablespoons of vegetable oil into the roasting tray and place in the oven. Peel and cut the potatoes into evenly sized pieces. Place potatoes in a large saucepan. Add enough cold water to just cover and bring to the boil for approximately 10 minutes. Drain thoroughly, then holding the lid firmly on the saucepan, shake vigorously to roughen the surfaces. Carefully remove the hot tray from the oven and place the potatoes gently into the hot oil, turn to coat and season. Place tray on the middle shelf of the oven.
During cooking: Turn half way through cooking. Cook until golden and soft in the middle. Do not allow to become too dark.
After cooking: Check food is piping hot.
