Cooks' notes:
• If you don't have a ricer or food mill, you can use a handheld masher, but the consistency of the potatoes won't be as smooth.
• Mashed potatoes can be made 1 day ahead and chilled, covered. Bring to room temperature, then reheat in a microwave or double boiler, stirring occasionally.
