Ingredients
2 pounds Yukon gold potatoes, peeled and cut into 1-inch cubes
Coarse salt
1/2 cup (1 stick) unsalted butter, cubed
1 1/2 cups buttermilk
Freshly ground white pepper
Preparation
Place potatoes in a pot of salted water and bring to a boil over medium-high heat. Reduce heat to a simmer and cook until potatoes are easily pierced with the tines of a fork, 12 to 15 minutes.
Add butter to potatoes and, using a handheld masher, mash butter into potatoes. Gradually add buttermilk, mashing until desired texture is achieved. Season with salt and white pepper; serve.
