Ingredients

  • 5 pounds russet potatoes, peeled and diced, and boiled until fork-tender
  • 8 egg yolks
  • 1 stick butter, softened
  • Salt and freshly ground black pepper
  • Nutmeg
  • 1 1/4 cup heavy cream
  • 1 whole egg

Directions

  1. 1
    Preheat the oven to 375 degrees F. Line a baking sheet with parchment or a silicon baking mat.
  2. 2
    Lay the boiled potatoes on a baking sheet and place into the oven until slightly dried on the surface, 10 to 15 minutes.
  3. 3
    Remove the potatoes from the oven and process through a ricer or food mill.
  4. 4
    Allow to cool in a bowl for about 5 minutes.
  5. 5
    Add the egg yolks, butter, a couple generous pinches of salt, a generous pinch of pepper, a pinch of nutmeg and 3/4 cup cream.
  6. 6
    Stir with a rubber spatula to combine.
  7. 7
    Taste and make sure the potatoes have been adequately salted.
  8. 8
    Transfer to a large pastry bag and pipe through a large star tip in a circular/upward spiral motion onto the prepared baking sheet.
  9. 9
    Make an egg wash by mixing the whole egg with the remaining 1/2 cup cream.
  10. 10
    Lightly brush the piped potatoes with the egg wash. (This is a little easier if you chill the piped potatoes for half an hour or so.)
  11. 11
    Bake until golden brown around the edges.
  12. 12
    Serve on a pretty platter!
