Gattò di Patate Napoletano
Naples' potato cake — a thick round of mashed potato enriched with eggs, butter, Parmigiano, salame napoletano, and mozzarella, baked until golden. The name comes from the French 'gâteau' — introduced during the Bourbon court of Naples when French culinary terminology entered Neapolitan vocabulary. The filling of salami and mozzarella is layered into the centre of the potato so that slicing reveals the filling. A dish for using up excellent leftover mashed potatoes or an excellent preparation in its own right.

The Method
1
Place the potatoes, unpeeled, in a large pot of cold salted water. Bring to the boil and cook until a skewer passes through the centre without resistance. Drain immediately and peel while still hot — handling them with a cloth if necessary. Pass at once through a potato ricer into a wide bowl. Do not press or work the purée beyond what the ricer demands. The result must be dry, light, and free of lumps.
2
While the riced potato is still hot, add the butter in pieces and work it in with a wooden spoon until fully absorbed. Add the grated Parmigiano, the beaten eggs, and the pinch of nutmeg. Mix to a smooth, uniform mass. Season with salt. The mixture must hold its shape when mounded — if it slackens or appears wet, the finished cake will not set.
3
Preheat the oven to 190 °C. Butter a round baking dish or cake tin of approximately 24 cm diameter generously on all sides and the base. Coat the interior entirely with breadcrumbs, tapping out any excess. The breadcrumb lining must be even and unbroken — it is the structural crust that holds the cake when sliced.
4
Spread half the potato mixture into the dish in an even layer, pressing it gently to the sides and base. Lay the sliced salame napoletano over the potato in a single layer, then distribute the cubed mozzarella evenly across the filling. Spread the remaining potato mixture over the filling, smoothing the surface level with the rim of the dish. The potato layers on each side must be substantial — a thin layer will crack and cannot support the filling.
5
This is where the dish lives or dies. Scatter a generous, even layer of breadcrumbs over the top surface and dot with small pieces of butter. Slide into the preheated oven and bake for 30 to 35 minutes. The top must turn a deep, even golden brown — not pale, not merely coloured. A pale crust lacks both flavour and the structural rigidity to survive slicing; the cake will collapse. When the crust is deep gold and the edges show the same colour pulling away from the dish, the gattò is done.
6
Remove from the oven and allow to rest in the dish for 10 minutes before cutting. This rest allows the interior to firm. Run a knife around the edge, then cut into wedges in the dish and lift each portion with a palette knife. The slice must hold its form, showing the filling as a distinct band at the centre.

Quality Hierarchy
01
Reserve — Potatoes: old-season Neapolitan floury varieties riced while still steaming. Mozzarella di bufala campana DOP, thoroughly dried. Salame napoletano of artisan production with visible fat marbling. Parmigiano-Reggiano aged 24 months, grated to order.
02
Estate — Good floury potato (Maris Piper, King Edward). Fior di latte of reliable provenance, squeezed and rested. A reputable southern Italian salame. Parmigiano-Reggiano aged 18 months from a named producer.
03
Market — Standard supermarket floury potato. Vacuum-packed fior di latte, well dried before use. Good branded salame napoletano or a comparable Italian cured sausage. Pre-grated Parmigiano of acceptable quality.
04
House — Any floury potato, thoroughly dried. Block mozzarella as a last resort, cubed and dried. A mild Italian-style salami. Grana Padano in place of Parmigiano.

Sensory Tests
◇Touch. A skewer passes through the whole unpeeled potato without resistance — boiling is complete.
◇Touch. The enriched potato mass holds its shape when mounded on the spoon — it is neither slack nor wet.
◇Sight. The breadcrumb lining coats every surface of the buttered dish evenly, with no bare patches.
◇Sight. The top crust is a deep, uniform golden brown and the edges show colour pulling away from the dish — baking is complete.
◇Touch. After the 10-minute rest, a wedge cut from the dish holds its form when lifted on a palette knife — the cake has set.
◇Where it lives or dies. The top crust must reach a deep, even golden brown — a pale gattò lacks both flavour and the structural rigidity to survive slicing.

What to Pour
A medium-bodied southern Italian red with sufficient acidity to cut the richness of egg-enriched potato, melted cheese, and cured salami — Aglianico del Taburno or a young Lacryma Christi rosso from Campania serve the dish well. A chilled Falanghina, the white of the same region, is the alternative for those who prefer white wine at table.
