  • 3 tsp. kosher salt, divided

For the Gnocchi Parisienne

  • Heat butter and milk in a medium pot, and bring to a boil.

  • Heat up a medium rondeau pot with heavily salted water to 180° (it shouldn’t be boiling).
  • Add gnocchi dough to a pastry bag and cut 1 inch off the pastry bag’s tip. Using scissors, cut gnocchi into 1½-inch pillows as the mixture comes out of the bag, letting the pieces fall into the salted water. Cook for 4½ minutes.
  • Using a slotted spoon, remove gnocchi from water and add to an ice bath. Once gnocchi has fully cooled down, remove from ice bath and place on a paper towel-lined tray.
  • Bag the gnocchi in 6-ounce portions and store in the refrigerator until ready to use.
