Frittata di Cipolle e Pecorino alla Calabrese

Calabria — Citta di Tropea e Provincia di Crotone

A thick, oven-finished frittata built on slow-caramelised Tropea red onions and aged Pecorino Crotonese — Calabria's answer to the Spanish tortilla. Onions are cooked low and long in olive oil until jammy, then the egg mixture is poured in and the frittata finished under the grill for a bronzed top. The sweetness of Tropea onions against pungent pecorino and fruity Calabrian olive oil creates a balance that defies its simplicity.

Sweet jammy onion, sharp aged pecorino, fruity Calabrian olive oil, faint chilli warmth — rich and satisfying with clean finish

{"Use Cipolla Rossa di Tropea IGP — their exceptional sweetness comes from volcanic soil and mild sea climate; regular red onions will not replicate this","Cook onions minimum 25 minutes over medium-low heat; they must be translucent and jammy, not crisp","Beat eggs lightly — over-beating incorporates excess air producing a foam texture rather than dense, creamy curds","Use Pecorino Crotonese stagionato (minimum 6 months) grated coarsely so it melts into pockets rather than uniformly blending","Finish under grill 3–4 minutes for bronzed top; the centre should remain slightly trembling when removed"}

{"Add a pinch of dried Calabrian chilli to the onion soffritto for authentic regional heat","Rest 5 minutes before cutting — eggs continue to set and the frittata becomes easier to slice cleanly","Serve at room temperature like Calabrians do — cold suppresses the onion sweetness and pecorino aroma","A splash of dry white wine added to onions halfway through cooking deepens caramelisation"}

{"Under-caramelising the onions — they need full sweetness development before eggs go in","Too-high heat causing rubbery eggs and burnt bottom before top sets","Using fresh rather than aged pecorino which makes the frittata watery and lacks sharpness","Flipping rather than grill-finishing — traditional Calabrese method keeps frittata thick and moist inside"}
