Homemade Gnocchi

Rinse the potatoes thoroughly. Cook for 25-30 minutes in boiling salted water until tender. Remove from the water and drain thoroughly. Cool slightly, and let dry. Peel the potatoes, and pass through a ricer. Spread the potatoes on a work surface, then season with salt and nutmeg. Sprinkle the flour over the potatoes, add the egg, andmix until a smooth dough has formed. Form 1/3 of the dough into a finger-thick roll on a floured surface. Cut into 1 cm (approximately 1/2 inch) long pieces, then indent the pieces with the tines of a fork. Repeat the process with the remaining dough, then cover and let rest. Place the gnocchi into boiling salted water, and cook for 3-4 minutes until they rise to the top.
