Ingredients

serves 6

　　2 pounds medium russet and/or Yukon Gold potatoes

　　1 tablespoon coarse salt, plus more for seasoning

　　5 tablespoons unsalted butter

　　1 1/2 pounds garden peas, shelled (1 1/2 cups)

　　1 cup milk

　　Freshly ground pepper

　　

Step 1

Peel and cut the potatoes crosswise into 1 1/2-inch-thick slices. Place the slices in a medium saucepan, and cover with cold water. Bring to a boil over medium heat; add 1 tablespoon salt. Reduce to a low simmer, and cook until the potatoes are tender when pierced with a knife, about 15 minutes. Transfer to a colander; let drain.

　　

Step 2

Meanwhile, melt 1 tablespoon butter in a small sauté pan over medium-low heat. Add the peas, and cook until they are tender and bright green, 4 to 5 minutes. Transfer to the jar of a blender, and add the milk; blend until the mixture is smooth and combined.

　　

Step 3

While still hot, pass the potatoes through a ricer or food mill into a large heatproof bowl. Stir with a wooden spoon until they are smooth, about 1 minute. Using a whisk, incorporate the remaining 4 tablespoons butter. Whisking constantly, add the pureed pea mixture, and season with salt and pepper. Serve immediately, or keep warm over a pan of simmering water.
