• Add a pinch of salt to a pan of boiling water, add the potatoes and reduce the heat and boil 20mins.
• In the meantime, preheat the oven to 180c, add the oil to a roasting dish and heat in an oven.
• Drain the potatoes in a colander and shake a few times to make the potatoes edges slightly roughed up.  Tip into the hot oil, roll over and cover each potato in oil and place in the oven for 60mins.
• Half way through cooking, turn the potatoes over.
• Once all crispy, serve immediately.

• Sunflower oil isn't recommended, I always find my potatoes burn
