For really crunchy roast potatoes with fluffy middles choose a floury variety of potato, such as Irish Roosters and try to make sure that they are all similar in size. To ensure really crispy roast potatoes drain off any excess fat about 20 minutes before the end of the cooking time. This will help them to go really crispy and golden brown around the edges.

Ingredients

  • 1kg potatoes, halved
  • 75g goose or duck fat
  • Small handful fresh rosemary sprigs
  • 6 whole garlic cloves (not peeled)
  • Sea salt

Method

  • Preheat the oven to 220C (425F), Gas mark 7. Place the potatoes in a pan of cold salted water and bring to the boil. Reduce the heat and simmer for 8-10 minutes until the outsides have just softened. Drain and return to the pan for a minute or two to dry out, shaking to knock off all the hard edges.
  • Meanwhile, preheat a roasting tin with the goose or duck fat for a few minutes until just smoking. Roughly prod the outside of the potatoes with a fork and toss them with rosemary and garlic. Carefully tip them into the hot oil, basting the tops. Roast for about 45 minutes to 1 hour, turning occasionally, until crisp and golden.
  • Transfer the roast potatoes with a slotted spoon into a warmed serving bowl and season with the sea salt and serve immediately.
