Roast potatoes with sage

Method

1. Preheat the oven to 200°C/fan180°C/gas 6. Put the potatoes in a pan of cold salted water, cover and bring to the boil, then simmer for 5 minutes. Drain well, return to the pan over a low heat, then shake the pan vigorously to rough up the edges of the potatoes.
2. Melt the goose fat in a large roasting tin in the oven for 2-3 minutes until really hot, then remove the tray and carefully tumble in the potatoes. Toss to coat, then roast for 40 minutes, turning occasionally, until golden and crisp. Add the sage leaves and a good sprinkling of flaky sea salt, then cook for a further 10-15 minutes.
