Place the peeled potatoes in a big pot and fill with cold water. Bring to a boil and cook them until a fork slides in easily, around 15-20 minutes. Drain off all the water.

Push the cooked potatoes through a ricer into a bowl (or mash until completely lump-free). Mix in the cream, 2 tablespoons of the melted butter, nutmeg, salt, and pepper until smooth. Let it cool a little, then mix in the egg yolks, one at a time.

Spoon the potato mixture into a piping bag with a large star nozzle. Pipe out 12 spiraled mounds onto the prepared tray (each should be about 2½ inches wide and 2 inches high). Give the tops a coat of the leftover melted butter.

Bake for 20 minutes, or until the edges start to brown. Sprinkle with parsley and enjoy warm.
