Swedish ‘Fan’ Potatoes

The curious name derives from that of a restaurant in Sweden which invented the method of part-slicing the potatoes in a fan shape before roasting. For extra flavour, strew some unpeeled garlic cloves in the roasting dish, which will perfume the oil with which the potatoes are basted. The garlic is roasted to a creamy purée which is scooped out of its skin on the plate. Cook the potatoes in an ovenproof dish which can go straight to the table.
