Mustard Mashed Potatoes

Preparation

1. Step 1

   In a 5-quart kettle or pot, cover the potatoes with cold salted water by 2 inches and simmer until tender, 35 to 45 minutes. While potatoes are simmering, in a small saucepan, heat the milk with the butter over moderate heat until the butter is melted. Remove from the heat and keep the milk mixture warm, covered.

   Step 2

   In a colander, drain the potatoes and cool just until they can be handled. Peel the potatoes, transferring to a large bowl. Add the mustard, salt and pepper to taste, and three-fourths of the hot milk mixture. With a potato masher, mash until smooth, adding more milk mixture if necessary to make the potatoes creamy.
