Ingredients

  • 1 pound (450 grams; about 2 large) russet or Yukon Gold potatoes, peeled and quartered
  • Kosher salt
  • ¼ cup (60 ml) heavy cream
  • 2 tablespoons (30 grams) unsalted butter
  • 1 tablespoon (15 grams) crème fraîche or sour cream, plus more to taste
  • 2 garlic cloves, minced
  • Freshly ground black pepper
  • 1¼ ounces (35 grams) finely grated Parmigiano-Reggiano
  • 1½ tablespoons minced fresh chives

Directions

  1. Add the potatoes to a pot and cover with an inch or two of cold water. Season generously with kosher salt and bring to a boil. Cook at a rapid simmer until tender and easily pierced with a knife, 10 to 15 minutes.
  2. While the potatoes cook, combine the cream, butter, crème fraîche, garlic, and a generous amount of black pepper in a small saucepan. Warm over medium-low heat, stirring often; when the cream starts to bubble, remove from the heat. Let the mixture stand for 10 minutes, or until the potatoes are ready.
  3. Drain the potatoes thoroughly. While they’re still warm, pass them through a ricer into a heatproof bowl. Fold in the cream mixture and Parmigiano-Reggiano and mix until well combined. Season to taste with salt and lots of black pepper, and add a touch more crème fraîche if you’d like. Stir in the chives.
  4. Transfer the filling to a piping bag or keep it in the bowl. Use warm or at room temperature, or refrigerate in an airtight container for up to 2 days and let soften at room temperature for 30 minutes before use.
