To prepare this potato balls recipe, start by washing thoroughly the potatoes. Peel the potatoes and place them in a large saucepan. Cover with cold water and bring to the boil. Lower the heat to a gentle simmer and cook for about 30 minutes. (For this potato balls recipe the potatoes need to boil, until very tender.)

Drain the potatoes in a colander, place them in a large bowl and mash them, using a fork or a masher. Add the rest of the ingredients, season with salt and pepper and blend to combine. Cover the bowl with some plastic wrap and place the mixture in the fridge for 1-2 hours, until firm enough to form the potato balls.

Form the mixture into little potato balls (this mixture is enough for 25 potato balls) and dredge in some flour shaking off any excess. Dip them in the egg and dredge them in powdered breadcrumbs. Fridge the potato balls for 1 more hour.

Fry the potato balls in a non-sticking pan with plenty of oil, until nicely colored and drain them on some kitchen paper. (Tips: Heat the oil until very hot and fry the potato balls in batches. If the surface of the pan is overcrowded then the temperature of the oil will decrease and your potato balls will not be crispy any more.)

Serve the potato balls while still warm with some mustard (or mustard-mayo sauce) as a delicious starter. Enjoy!
