Mix all the dry ingredients, then add the liquid except the milk.
Add the milk a few tbs at a time, just until you have a nice and soft (but not sticky) dough.
Make some logs out of it and cut same size pieces, about the size of a small walnut.
Preheat the oil at 330-340° F (165-170°C).
Fry 5-6 castagnole at a time for about 4 minutes, or until golden.
Drain and put them on a kitchen paper towel.
Toss them in sugar and serve once cold.
