Transfer the mixture to a large tray, and spread about 1.5 cm thick, and let cool.
Once the mixture is cold (room temperature), add a little bit of nutmeg over the top. Cover with film, and store it in the refrigerator until cold.
Prepare a bowl with the beaten eggs, and another bowl with the bread crumbs.
With a sharp knife, divide the croquettes dough in equal portions, with each portion, try to form a cylinder (see pictures for guidance)
Dip each cylinder in the beaten eggs, and cover them with bread crumbs, and once the croquettes are fully covered with bread crumbs, transfer the croquettes to a plate. Repeat this process with the rest of the croquettes dough.
In a medium size frying pan, hit the vegetable oil, and we will fry 3-4 croquettes at a time until they acquire a golden color.
Transfer the croquettes to a plate, and serve them immediately.
