Mashed Potatoes with Herb-Infused Cream and Chives

You can peel the potatoes the day before, then cover with cold water and refrigerate until ready to cook. Alternatively, you can cook and mash the potatoes up to 2 days in advance. Let them cool to room temperature, then transfer to an airtight container and refrigerate. Just before serving, pour a thin layer of milk onto the bottom of a wide, heavy pot. Add the mashed potatoes, set the pot over medium heat and stir occasionally until the potatoes are hot.
