Step 1

Put potatoes in a heavy pot filled with cold water and season liberally with salt. Bring to a boil over high heat then reduce heat to medium and simmer, uncovered, until potatoes are soft, about 20 minutes.

While potatoes cook, heat milk in a small saucepan over moderately high heat until it just comes to a simmer. Turn off heat under saucepan and add scallions to milk.

Drain potatoes well, then return them to pot and place over low heat. Warm potatoes for a couple of minutes, occasionally shaking pot. (This will help dry out the potatoes, making a fluffier mash.) Using a potato masher or fork, mash potatoes until almost smooth. Cut 4 tablespoons butter into potatoes, pour in milk and scallions, and season with 1 teaspoon salt. Continue to mash until potatoes are smooth. Transfer to a warmed serving bowl, make a wide depression in the center and nestle remaining 2 tablespoons butter into hollow. Serve immediately.
