This classic French accompaniment hides two potatoes in one—a crisp, elegantly swirled exterior encloses a fluffy, nutmeg-spiced interior.
Yield: serves 4


  • 2 12 lb. russet potatoes (about 4)
  • 4 tbsp. unsalted butter, softened
  • 2 egg yolks, plus 1 whole egg mixed with 1 tsp. heavy cream, lightly beaten
  • 18 tsp. freshly grated nutmeg
  • Kosher salt and freshly ground black pepper, to taste


  1. Heat oven to 400°. Using a fork, prick potatoes all over; place on a baking sheet. Bake until tender, 1 12 hours; let cool, then peel and pass through a food mill or ricer.
  2. Mix potatoes, butter, yolks, nutmeg, salt, and pepper in a bowl; transfer to a piping bag fitted with a 34” star tip. On a parchment paper-lined baking sheet, and working in a tight circular motion, pipe twelve 2 12” cones about 2″ high. Brush with egg mixture; bake until golden brown, 40–45 minutes.
