Classic roasties with garlic and rosemary

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, return to a low heat and shake the pan to roughen up the potatoes.
2. Melt the fat in a large roasting tin in the oven until really hot, then carefully add the potatoes, garlic and rosemary. Toss well and roast for 50 minutes-1 hour, turning occasionally, until crispy. Season with sea salt to serve.
