Step 1

In a Dutch oven or large stockpot, add potatoes and 2 tablespoons salt. Add cold water to cover potatoes by 1 inch.

Step 2

Over medium-high heat, bring to boil and partially cover pot. Cook until potatoes are tender and a fork can be easily slipped into the center, stirring once or twice, about 10 to 15 minutes. Drain well, tossing in colander to remove excess water.

Step 3

Wipe pot dry. Return potatoes to pot and mash to a uniform consistency. Using a rubber spatula, fold in melted butter until just incorporated.

Step 4

Slowly stir in 1 1/2 cups hot milk. Add more milk, 1 tablespoon at a time, to adjust the consistency as desired. Season to taste with salt and pepper.
