Mashed Potato Tartlets

Peel and dice the potatoes into cubes

Place them in a pan with the water, butter, cinnamon, and nutmeg

Cook over low heat until the potatoes are cooked through but still firm

Roll out the pastry dough with a rolling pin and cut it into round biscuits using a biscuit cutter

Arrange the pastry discs on a baking sheet lined with parchment paper and top them with the mashed potato cubes

Place in the hot oven until the pastry is crispy and dry

Remove from the oven and dust with confectioner's sugar over the still-warm tartlets
