A classic four-step wonder of a recipe that will give you perfect potatoes every time. The secret? Goose fat.
Preheat the oven to 220C/425F/Gas 7.
Peel the potatoes and cut into large chunks. Parboil in boiling salted water for 5 minutes. Drain and toss in the pan to roughen the edges.
Put a generous amount of olive oil or goose fat in a roasting tin and put in oven, until smoking. Carefully take the tin out of the oven and add the potatoes to the hot fat, basting them as you do so.
Put the tin back in the oven and cook for about 1 hour until the roast potatoes are golden and crunchy on the outside and soft in the middle. Turn them over from time to time whilst they are cooking to make sure they colour on all sides.
