  • 1/4 cup whole milk
  • 8 tablespoons of butter
  • 1/2 cup full-fat sour cream
  • Kosher salt and black pepper to taste
  • Optional: fresh chives or fresh parsley for garnish

Instructions

  • Peel and quarter the potatoes, then place the potatoes in a large pot. Cover with cold water and add a generous pinch of kosher salt.
  • Bring to a boil over high heat, then reduce to medium heat and cook until fork tender, about 15–20 minutes.
  • While the potatoes cook, heat the milk and butter together in a small saucepan over medium-low heat until hot (but not boiling).
  • Drain the potatoes well and transfer them to a large bowl.
  • Mash using a potato masher, hand mixer, electric mixer, or potato ricer until smooth.
  • Pour the warm milk and melted butter mixture over the hot potatoes, then stir in the sour cream. Mix until creamy, adding a little milk if needed.
