How to roast potatoes

Recipe for perfect roast potatoes:

• Heat oven to 200C/180C fan/gas 6 and preheat a baking tray and fat (such as sunflower oil or duck or goose fat).
• Peel and cut the potatoes into halves or quarters so they're all roughly the same size.
• Transfer to a pan of cold water, then bring to the boil and cook for 2 mins.
• Drain in a colander, then add a sprinkling of flour and salt and shake the colander to roughen the edges of the potatoes.
• Tip the potatoes onto the hot baking tray, then coat in the hot fat and roast for 1 hr until golden and crispy. Turn the potatoes over once or twice during cooking.

Which fat makes the best roasties?

The Good Food team tested different types of fats, from traditional drippings to plain old butter to discover what produces the crispiest potato. Although coconut oil was best for added crunch, we found that goose fat gave the best overall flavour. Butter makes a good vegetarian alternative for golden brown tatties.
