Risotto con pesce persico

Lake perch (Perca fluviatilis) was introduced to Italy's prealpine lakes from Switzerland around the mid-18th century, rapidly colonising the cold, oxygen-rich waters of Lake Como (Lario) and supporting a commercial lakeside fishing economy that endured well into the 20th century. The pairing with risotto belongs to Lombardy's certosina tradition, in which river and lake fish substituted for meat in monastic kitchens during the Church's many fast days; rice cultivation in the Po plain, expanded by the Benedictines from the 15th century onward, provided the natural grain partner. The older preparation is riso in cagnone — rice boiled in salted water, its Lombard dialect name evoking the appearance of well-drained grains alongside simply prepared perch — which the mantecato risotto version eventually superseded for restaurant service. The dish's centrality to Como identity prompted the founding of a dedicated Accademia del Risotto al Pesce Persico to formalize and protect the canonical recipe.

Rice silky with mantecatura, subtly tinged with the lake; perch fillets crack at the golden crust, then yield flesh as sweet and delicate as freshwater allows, perfumed with browned butter and crisped sage.

Perch fillets dusted with flour develop a thin starch shell that undergoes Maillard browning in hot butter, forming an aromatic crust that seals moisture and contrasts with the delicate interior. Sage's volatile oils — borneol, camphor and thujone — are fat-soluble; they transfer efficiently into butter over low heat, then onto the fish surface during frying. In the risotto, Carnaroli's high amylopectin content releases free amylose into the cooking liquid with each agitation, progressively building the creamy sauce that coats the grains.
