Peel and quarter potatoes. Boil them in salted water until tender and then drain and place on a sheet pan. Allow them to dry out for about 4-5 minutes.
Now put the potatoes in a food mill and puree. Blend in the unsalted butter, nutmeg, salt and pepper. Mix in the egg and egg yolks, blending well.
Place mixture in a pastry bag with a star tip. Pipe in a spiral form onto a sheet pan lined with parchment paper and brush the top of each piped potato with clarified butter.
Bake in a preheated 375 degree oven for 8-10 minutes.
