Crocchè Napoletani

Ingredients

• 1 kg floury potatoes, unpeeled, boiled whole
• 3 egg yolks, room temperature
• 60 g Parmigiano Reggiano or pecorino, finely grated
• 1 small bunch flat-leaf parsley, finely chopped
• 1 pinch nutmeg, freshly grated
• to taste fine salt and black pepper
• For the crocchè ripieni (optional)
• 100 g fior di latte or provola, cut into small cubes, frozen before use
• For the coating
• 100 g plain flour
• 2 eggs, beaten
• 150 g fine dried breadcrumbs
• For frying
• 1 litre neutral frying oil, sufficient for abundant depth

Method

1. 1
   Place the unpeeled potatoes in a pot of cold salted water. Bring to the boil and cook until a skewer passes through the centre without resistance. Drain immediately.
2. 2
   Peel the potatoes while still hot — hold them in a cloth — and pass them through a ricer directly onto a clean work surface or into a wide bowl. Do not mash by any other means. The mixture must be smooth, dry, and without lumps; steam rising freely is the sign the moisture is escaping correctly.
3. 3
   Allow the riced potato to cool until it is warm but no longer steaming. Work in the egg yolks, grated cheese, chopped parsley, a pinch of nutmeg, salt, and black pepper. The mixture should come together as a firm, cohesive mass that holds a clean shape when pressed — this is where the dish lives or dies: too warm and it will collapse in the oil; too little egg yolk and the interior will be dry and mealy.
4. 4
   Chill the mixture for at least 30 minutes. Divide into portions of approximately 60 g each. For the plain version, roll each portion between the palms into a cylinder roughly the size of a large thumb. For the ripieni version, flatten each portion, place one frozen cube of fior di latte or provola at the centre, and enclose it completely, sealing all edges before rolling. The surface should be smooth and show no cracks.
5. 5
   Chill the shaped crocchè for a further 30 minutes. Set out three shallow dishes: one with flour, one with beaten egg, one with breadcrumbs. Roll each crocchè in flour, shaking off any excess; dip in beaten egg until fully coated; roll in breadcrumbs, pressing gently to adhere. For an extra-crispy shell, repeat the egg and breadcrumb stages a second time. The finished crocchè should have an even, opaque coat with no bare patches.
6. 6
   Heat abundant oil in a deep, heavy pan to 170–175°C. Fry the crocchè in small batches — do not crowd the pan — turning once, until the exterior is deep golden on all sides. An audible, sustained sizzle throughout cooking confirms the oil temperature is holding; a faltering sizzle indicates the oil has dropped and the crocchè will absorb grease.
7. 7
   Lift the crocchè with a slotted spoon and drain on absorbent paper. Serve immediately. The crust should crackle audibly at the first bite; the interior must be creamy, smooth, and fully hot through.
