First, boil the well washed potatoes for about 35 minutes or until they are nice and soft, then drain, peel and mash them.
Combine flour, yeast and potatoes in a bowl, then gradually begin to incorporate the water and finally the salt: you will have to obtain a very soft mixture (almost a batter), but quite homogeneous.
Cover the bowl with a clean cloth moistened with water and let it grow in a sheltered place for about 2 hours or until it has at least doubled in volume, full of bubbles.
With the help of a couple of spoons, fry the dough in hot oil creating balls: once golden, lift them with a skimmer, place them on kitchen paper to remove excess oil, then immediately pass them in the sugar.
That's all: the Christmas pettole are ready, serve them immediately.
