Calzone Pugliese — Baked Pizza Dough Turnover with Onion and Olives
Calzone pugliese is not the fried calzone fritto of the Neapolitan street tradition but rather a baked, large turnover of leavened pizza dough filled with slow-cooked sweet onions, black Cerignola olives, salted anchovies, and capers — a preparation that is simultaneously a bread, an antipasto, and a meal. The filling is always vegetable-based in the traditional version; the onions are cooked until completely sweet and caramelised before they go inside; the olives and anchovies are the salt and umami notes. Baked in a very hot oven until the crust is golden and blistered, the calzone is then rested and eaten at room temperature — it is never a hot emergency food but a prepared, considered preparation.

The Method
1
Combine the 00 flour, yeast, and salt in a large bowl. Add the olive oil and lukewarm water gradually, mixing until a cohesive dough forms. Knead on an unfloured surface for 10 minutes. The dough is ready when it is smooth, elastic, and springs back cleanly when pressed with a finger.
2
Shape the dough into a ball, place in a lightly oiled bowl, cover, and prove at room temperature for 2 hours. The dough is ready when it has doubled in volume and a finger pressed into its surface leaves an indent that rebounds slowly.
3
Place the thinly sliced onions in a wide, heavy pan with the olive oil over the lowest possible heat. Cook uncovered, stirring occasionally, for 45 to 60 minutes. This is where the dish lives or dies: the onions must become completely sweet, golden, and collapsed — never browned, never sharp. At no point should they colour deeply or catch at the edges. Remove from the heat and cool completely, or refrigerate overnight.
4
Once the onions are completely cold, combine them with the pitted Cerignola olives, desalted anchovy fillets, rinsed capers, and black pepper. Mix gently. The anchovies will begin to break apart into the onion. The filling must be cold before it goes near the dough.
5
Heat the oven to 220 °C. On a lightly floured surface, roll the proved dough to a circle of approximately 30 cm diameter. Arrange the filling evenly over one half of the circle, leaving a 2 cm border clear at the edge. Fold the bare half of the dough over the filling to form a half-moon. Press the edges together firmly, then fold and crimp the sealed edge to ensure no filling can escape. The seal is sound when the border holds its shape without splitting.
6
Transfer the calzone to a lightly oiled baking sheet. Score the top surface 3 to 4 times with a sharp knife to allow steam to vent. Brush the entire surface generously with olive oil. Bake at 220 °C for 25 to 30 minutes. The calzone is done when the crust is deep golden, blistered in places, and sounds hollow when tapped on its underside.
7
Remove from the oven and rest on a wire rack for a minimum of 20 minutes before cutting. The calzone is eaten at room temperature. Slice into thick wedges; the filling should hold together, the onion fragrant and collapsed, with no excess moisture.

Quality Hierarchy
01
Reserve — Large, meaty Cerignola black olives sourced from a Pugliese producer; salted whole anchovies from the Adriatic, desalted and filleted by hand; single-estate Pugliese extra-virgin olive oil; stone-milled 00 flour.
02
Estate — Cerignola olives from a named Italian importer; good-quality salt-packed anchovies in tins; a reliable cold-pressed extra-virgin olive oil; standard supermarket 00 flour.
03
Market — Gaeta olives as a stated alternative to Cerignola; oil-packed anchovy fillets in jars; any mild, fruity extra-virgin olive oil; 00 flour of any standard brand.
04
House — Any large, meaty black olive; tinned anchovy fillets in oil; light olive oil; strong white bread flour in place of 00.

Sensory Tests
◇Touch. The proved dough springs back slowly — but not fully — when pressed with a fingertip, indicating full fermentation without over-proving.
◇Smell. The onions smell sweet and faintly caramelised after their long cooking; any sharp or raw onion smell means they need more time.
◇Touch. The crimped edge holds firmly without cracking or splitting when the calzone is lifted — the seal is sound.
◇Sound. The baked calzone sounds hollow when tapped on its underside, indicating the crust is fully set and the interior has steamed through.
◇Sight. After resting, cut wedges show a cohesive, glistening onion filling with no pooling of liquid — the rest has allowed the steam to redistribute.
◇Where it lives or dies. The onions must cook over the lowest possible heat for the full 45 to 60 minutes until completely sweet, collapsed, and without any trace of harshness — pale or undercooked onions render the filling sharp and the calzone inedible.
