Boil the potatoes in lightly salted water until soft and cooked. Drain and let them cool. Once cooled, peel the potatoes and mash them lightly. Set aside in a large bowl.
In a sauce pan, melt the butter. Once the butter is melted, add the cream and mix well.
Pour the butter-cream mixture over the boiled potatoes and mash them with a masher.
When the potatoes are all broken down, use a strong wooden spoon to beat it further while pouring the milk at the same time. Beat the potatoes until creamy and smooth. Make sure not to overbeat it as it may turn the potatoes gluey.
Serve warm with roast chicken.
