Gnocchi di Susine

Plum dumplings are documented as a dish of the Austro-Hungarian Empire, spreading across its Slavic and German-speaking lands under a family of cognate names — the Hungarian szilvásgombóc, the German Zwetschgenknödel, the South Slavic knedle, all built on Knödel, the German word for dumpling. Trieste inherited the dish through its long centuries as the Habsburg Monarchy's principal seaport: declared a free port in 1719 under Emperor Charles VI and Austria-Hungary's great commercial gateway until it passed to Italy in 1918-1920, the city sat where Latin, Slavic and Germanic worlds met. Triestine cuisine accordingly blends Mediterranean and Mitteleuropean cooking, and gnocchi di susine is one of its emblematic sweets, the local form of a recipe also claimed by Slovenia, Croatia, Austria and Bohemia. No single inventor or founding date survives; it is a shared folk dish of the old empire, adapted in Trieste with the Italian potato gnocchi dough. Italian cooks fix its season to late summer, when prune plums (susine, the small oval damaschine or Italian prune plum) ripen.

A finished dumpling is pale and soft, its breadcrumb coat crisp and buttery, faintly sweet with cinnamon. Bitten open, the potato shell gives way at once and the plum bursts — its juices have stewed inside the dough into a hot, jammy pool, the sugar cube melted away, the skin tart against the sweetness of the crumbs. The contrast is the whole point: a near-savoury, pillowy starch wrap holding a sharp, syrupy fruit core, with the toasted crumbs adding crunch and a nutty warmth. Served fresh and hot; left to stand, the shell turns gummy and the crumb coat goes soft.

The dish works by cooking three things at once in one envelope. The potato dough is a gelatinised-starch matrix: boiled potato is riced and bound with flour and egg, kept barely worked so the gluten stays slack and the gnocco stays tender rather than rubbery — over-kneading or wet potato forces in more flour and toughens it. Sealed inside, the plum is effectively steamed in its own juice; the heat ruptures its cells, its pectin and sugars dissolve, and the tucked-in sugar cube draws water out by osmosis to build the syrupy centre while balancing the skin's malic acid. The breadcrumb coat is the textural and flavour finish: bread toasted in butter undergoes the Maillard reaction and the butter's milk solids brown, giving the nutty, caramel notes and a crisp shell that clings to the hot, slightly sticky dumpling. Boiling is gentle and brief — the dumplings are done moments after they float, and a hard boil would split the dough and spill the plum.
