Peperonata Piemontese — Sweet Pepper Stew
Piedmont produces some of the finest sweet peppers in Italy — the Corno di Bue (bull's horn) peppers of the Asti area, thick-walled, sweet, and bright red, roasted or braised into the definitive peperonata: a long, slow stew of peppers, onion, tomato, and olive oil that reduces over an hour into a dense, sweet, slightly jammy preparation that is simultaneously a condiment, a side dish, and a sauce for meat. The Piedmontese peperonata is notably slower and denser than southern versions — the peppers are cooked until they nearly dissolve. It is one of the fundamental preparations of the Piedmontese summer table.

The Method
1
Place each pepper directly over a gas flame or directly under a hot grill. Turn as needed until the skin is completely charred on all sides. Transfer to a bowl, cover, and leave to steam for 10 minutes. Peel away the blackened skin entirely — no charred skin should remain — then remove the seeds and tear the flesh into broad strips. The flesh should be supple and bright red throughout.
2
Warm the olive oil in a wide, heavy pan over low heat. Add the sliced white onion and a pinch of salt. Cook uncovered over low heat, stirring occasionally, for 15 minutes. The onion must be fully softened and translucent, with no colour taken on.
3
Add the pepper strips, the crushed peeled tomatoes, the white wine vinegar, and the measured salt. Stir to combine. This is where the dish lives or dies: the heat must remain very low and the pan uncovered for the full duration — too high a flame burns the peppers and drives off liquid before the flesh can collapse; too short a time leaves the preparation loose and raw-tasting rather than dense and jammy. Cook for 45 to 60 minutes, stirring occasionally, until the peppers are almost falling apart and the sauce has reduced to a dense, deeply coloured stew. No standing liquid should remain.
4
Taste and adjust salt. Remove from heat. The finished peperonata should hold its shape on a spoon yet spread slowly — the consistency is that of a thick jam. It may be served warm or at room temperature, and its flavour will deepen further after one to two days.

Quality Hierarchy
01
Reserve — Corno di Bue peppers from the Asti or Cuneo provinces, sourced at the height of the late-summer season: thick-walled, deep red, and at peak sweetness. Extra-virgin olive oil of Ligurian or Piedmontese origin. A good-quality aged white wine vinegar.
02
Estate — Corno di Bue peppers from a named Italian producer or specialist market; any single-origin extra-virgin olive oil of clean, mild character; a reliable white wine vinegar without sharpness.
03
Market — Any large, thick-walled sweet red pepper available from a good market — Ramiro or pointed red sweet peppers are acceptable substitutes. A clean extra-virgin olive oil. Standard white wine vinegar.
04
House — Supermarket sweet red bell peppers — the walls are thinner and the flavour less complex, but the method remains the same. Pure olive oil in place of extra-virgin. Any mild white vinegar.

Sensory Tests
◇Sight. The charred pepper skin lifts cleanly from the flesh in sheets; the flesh beneath is uniformly bright red with no raw or pale patches.
◇Sight. After 15 minutes of low cooking, the onion is fully translucent and soft, with no golden or brown edges.
◇Sight. At the end of the long braise, no standing liquid remains in the pan; the mass is a dense, orange-red stew that moves slowly when the pan is tilted.
◇Touch. A strip of pepper pressed between the fingers offers no resistance and begins to break apart — the flesh has fully collapsed.
◇Where it lives or dies. The heat must stay very low and the pan uncovered for the full 45 to 60 minutes: too much heat or too little time produces a loose, vegetable stew rather than the dense, jammy reduction that defines the Piedmontese preparation.
