Gatto di Patate Napoletano con Scamorza
Naples' beloved potato cake — a baked torte of mashed potato enriched with salami, Scamorza affumicata, Parmigiano, eggs, and lard, pressed into a buttered breadcrumbed baking dish and baked until golden and crusty. When cut, the interior reveals a matrix of melted smoked cheese, salami pockets, and potato — every forkful is different. The name 'gattò' is a Neapolitan corruption of the French 'gâteau' — a legacy of Bourbon court cooking in 18th-century Naples.

The Method
1
Boil the potatoes in their skins until completely tender. Drain, peel immediately, and pass through a potato ricer or mouli while still hot. Spread the mash briefly across the board or pan to allow steam to escape — the result must be dry. No butter, no cream is added at this stage. The mash is ready when it holds its shape and releases no visible moisture.
2
Work the lard, beaten eggs, and Parmigiano into the hot dry mash. Season with salt. Fold with a wooden spoon until the mixture is cohesive, uniformly enriched, and pulls cleanly from the sides of the bowl. The texture should be firm enough to hold a pressed layer without slumping.
3
Grease a deep round baking dish (approximately 24 cm diameter) generously with lard on base and sides. Coat the entire interior with a thick, even layer of breadcrumbs, pressing them firmly to adhere; tip out any excess. The base coat must be thorough — insufficient crumbing at the bottom causes the gattò to tear on turning out.
4
Press half the potato mixture into the dish in an even layer, smoothing it flat with the back of a wet spoon. Distribute the Scamorza cubes, salami pieces, and sliced hard-boiled eggs across the surface in a single filling layer. Spoon the remaining potato over the filling and press firmly and evenly to seal the interior completely. The top surface should be level with no filling visible at the edges — this is where the dish lives or dies: a loose or uneven press will cause the gattò to collapse when cut and the filling pockets will not hold their character.
5
Scatter breadcrumbs generously over the entire top surface and dot with the tablespoon of butter in small pieces. Place in an oven set to 180 °C. Bake for 40–45 minutes. The gattò is ready when the crust is deeply golden and the edges have pulled slightly from the dish; a pale surface indicates under-baking and insufficient textural contrast.
6
Remove from the oven and rest in the dish for 10 minutes without disturbance. Run a palette knife around the edges, invert a serving plate over the dish, and turn out in one decisive movement. The base crust should present as a uniform golden surface. Allow to cool for a further 2–3 minutes before slicing — the internal structure firms sufficiently for clean, defined portions.
III
Quality Hierarchy
01
Reserve — Neapolitan salami from a Campanian producer; Scamorza affumicata from a small-batch southern dairy; Parmigiano Reggiano aged 24 months minimum; home-rendered strutto.
02
Estate — Good artisan Scamorza affumicata and named Neapolitan-style salami from a reputable Italian deli; Parmigiano Reggiano aged 18 months; commercial strutto of clean flavour.
03
Market — Supermarket Scamorza affumicata (cut to cubes regardless); standard Italian salami; Grana Padano in place of Parmigiano; lard from a butcher.
04
House — Any smoked semi-firm cheese cut to cubes; cooked ham or mortadella in place of salami; Pecorino Romano; butter used in place of strutto, with the understanding that the result will be lighter and less traditional.

Sensory Tests
◇Touch. The dry mash holds its shape under a pressed finger and releases no moisture — no slump, no wet sheen.
◇Touch. The pressed potato layers feel firm and level; the filling layer is fully enclosed with no gaps at the rim.
◇Sight. After 40–45 minutes the top crust is deeply golden, approaching brown at the edges, and has visibly pulled from the sides of the dish.
◇Sight. On turning out, the base presents an unbroken, uniform golden crust with no tears or pale patches.
◇Touch. After 10 minutes' rest, the turned-out gattò yields only slightly when pressed at the centre — the internal matrix has set enough for clean slicing.
◇Where it lives or dies. The filling must be pressed between two firm, even layers of dry potato and sealed completely at the edges — a loose or uneven press collapses the interior structure and destroys the distinct pockets of molten Scamorza, salami, and egg that define the dish.
