Preparation

Wash the potatoes, put them in a pot, cover them with cold water and cook until when they can be pierced with a fork.
Drain, peel and mash them.
Add one egg, the Grana Padano cheese, the strips of salami, salt, pepper and stir until ingredients are well mixed.
Take some of the mixture with both hands and shape it into croquettes.
Soak the croquette into two beaten eggs and into breadcrumbs and repeat this process.
Deep-fry the croquettes in the seed oil, until when they are golden brown.
Lift croquettes from the oil with a skimmer, drain them on straw paper and serve while hot.
