Ingredients
4 tbsp goose fat or sunflower oil
2kg potatoes, peeled, halved if large
Method
Heat the oven to 220C/fan 200C/gas 7. Put the fat in a solid roasting tin and put in the oven to heat up. Cook the potatoes in a large pan of boiling water for 5 minutes. Drain well, then shake around in a colander to rough up the edges a bit. Tip the potatoes carefully into the hot fat and turn them over so each one is coated. Slide back in the oven for 40 minutes or until crisp and golden and cooked through (turn them over halfway through). Sprinkle with salt before serving.
