For potatoes, place them in a pot covered in cold water, bring to a boil, salt the water liberally, add the garlic and boil to tender 12-15 minutes. Drain and place in food mill or ricer and pass the potatoes and garlic through. Stir the milk and Boursin into the potatoes, add lemon zest and juice and adjust salt and pepper to taste. Transfer to a serving bowl and make a shallow well, top with melted butter and scatter with chives.
