Peel the potatoes, rinse then cut into three, place in deep saucepan well covered with water. Bring to a simmer and cook until very tender, approx 20 minutes.

Strain potatoes using a colander and set aside to drain thoroughly.

Using a ricer or a masher, mash the potatoes in a mixing bowl.

Melt the butter in microwave or on the stove and pour into potato mash. Add egg yolks, salt and pepper plus nutmeg. Mix well.

Grease a baking sheet pan with olive oil.

Place a large star nozzle in a piping bag, fill the bag and pipe swirls directly onto the sheet pan. You should have 16-20 for a good size.

Bake in oven for 15-20 min at 430°F – 220°C or until golden brown. Rotate the pan half way through cooking for even browning. Lift of the pan with a thin metal spatula and serve immediately.
