Bring the milk to the boil, then gradually sprinkle in the flour, stirring vigorously and continuously until you get a smooth mass that pulls away from the side of the pan.
Tip the mixture into a bowl and let it cool completely.
Add the salt and sugar, then beat in the egg yolks one at a time, mixing thoroughly with a wooden spoon after each addition, until you get a shiny dough that still holds its shape when scooped.
Heat plenty of oil or lard to 170°C in a deep pan.
Using two teaspoons, drop small dumplings of the dough directly into the hot fat.
Fry over medium heat, turning occasionally, for 4-5 minutes, until golden brown and cooked through inside.
Drain on paper towels, then while still warm dust with vanilla sugar.
Serve with apricot jam or warm wine-egg custard (borsodó) alongside.
