The Method
1
Heat the oven to 200 °C. Lay the pumpkin wedges cut-side down on a lined tray and roast until the flesh is completely tender and the cut surface has dried and coloured — no steam should rise when you press a wedge. Roasting, not boiling or steaming, is mandatory: residual water forces excess flour into the dough and kills the pumpkin character. The flesh is ready when a skewer meets no resistance and the tray shows no pooling liquid.
2
Scoop the flesh from the skin and pass it through a ricer while still warm. Spread the purée on a tray and leave it to cool completely. The purée must be dry enough to hold a ridge when drawn with a spoon; if it slumps flat, return it to the oven briefly on the tray to drive off more moisture.
3
This is where the dish lives or dies. Transfer the cooled purée to a bowl. Add the egg, nutmeg, cinnamon and a pinch of salt, then incorporate the flour a little at a time, working gently. Stop adding flour the moment the dough just holds its shape when rolled — it will be soft and slightly tacky. Pumpkin gnocchi need markedly less flour than potato gnocchi; pressing beyond that threshold produces dense, starchy dumplings with no pumpkin flavour. The correct dough is barely cohesive, yielding to the touch like a soft earlobe.
4
On a lightly floured surface, roll the dough into cylinders roughly 2 cm in diameter and cut into 3 cm lengths, shaping each piece into a blunt oval. Lay the formed gnocchi on a floured tray in a single layer without touching. They are ready to cook when they hold their shape and do not spread.
5
Bring a large pot of well-salted water to a rolling boil. Cook the gnocchi in batches — do not crowd the pot. They are done when they rise to the surface; hold them there for no more than 15 seconds, then lift with a slotted spoon. Longer cooking beyond the float collapses the structure.
6
While the gnocchi cook, melt the butter in a wide pan over medium heat with the sage leaves. Continue cooking, swirling occasionally, until the milk solids turn deep golden and the butter smells of toasted hazelnuts. Clarified butter cannot achieve this: the milk solids are the agent of browning. Remove from heat the moment the colour reaches amber — the pan's residual heat will carry it further if left on the flame.
7
Lift the gnocchi directly into the browned butter pan and toss briefly over low heat to coat. Plate immediately, finish with the grated Parmigiano, and scatter the coarsely crushed amaretti over the top at the last moment — adding them in the pan or under heat makes them soggy and eliminates the textural contrast that defines the dish. The finished plate should show distinct amber butter pooling at the edges, flecks of golden sage, and pale irregular shards of amaretti.
