6 pounds red potatoes, washed and cut into 2-inch chunks
2 sticks (1/2 pound) unsalted butter, softened
1 cup heavy cream
Freshly ground pepper
Put the potatoes in a large pot and cover with water. Cover the pot and bring to a boil.
Add a large pinch of salt and boil, uncovered, over medium-high heat until fork-tender, about 25 minutes.
Drain the potatoes and return to the pot.
Off the heat, lightly mash the potatoes. Add the butter and milk and mash until incorporated.
Season with salt and pepper and serve.
