This is no ordinary mashed potato, the dish served at Robuchon au Dome, a Michelin starred restaurant, is well worth a try. The smooth silky and soft mash has the perfect ratio of potato and butter for that out of this world flavour. Its made with French butter and ratte potatoes, so you can expect the best. Plus, the mash after being well stirred is passed through a sieve to achieve that extra velvety texture.
