Yield

Serves 10 (serving size: about 2/3 cup)

If making ahead, keep the potatoes warm by placing in a heatproof bowl, covering with plastic wrap, and setting over a saucepan of gently simmering water. This setup, called a bain-marie, will keep potatoes moist and warm without scorching them on the bottom. A ricer finely breaks up the cooked potatoes without activating the potato starches, which could make the consistency gluey. It also allows the butter and liquid, such as milk or buttermilk, to quickly incorporate so the mash is smooth and free of lumps. If you don’t have one, use a potato masher, being careful not to overwork the potatoes in the pan.

Ingredients

  • 1 1/2 pounds russet potatoes, peeled and cut into 1-in. pieces
  • 1 1/2 pounds Yukon Gold potatoes, peeled and cut into 1-in. pieces
  • 3 tablespoons unsalted butter, cut into pieces
  • 1 1/4 cups room-temperature nonfat buttermilk
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
