Garlic-Thyme Mashed Potatoes
Potatoes can be peeled and cut up to 2 days ahead. Store them in the refrigerator in an airtight container filled with water. Mashed potatoes can be made 2 hours in advance. Transfer them to a heatproof bowl, cover with plastic wrap, and place over a pot of simmering water. Uncover and stir to serve.
