Poc chuc cebollas asadas (charred Yucatecan pickled onion)
Cebollas asadas are Yucatán's iconic condiment — white onion halves charred directly on a comal until black and softened, then marinated in habanero-lime juice while still warm. The charring creates sweetness from caramelisation while the outside blackens. The warm onion absorbs the habanero-lime marinade deeply. Served alongside poc chuc, cochinita pibil, and any Yucatecan grilled meat as an essential accompaniment — not optional garnish.

The Method
1
Set a dry comal or heavy cast-iron skillet over medium-high heat. Place the onion halves cut-side down directly on the dry surface — no oil. Place the whole habanero alongside. Char without moving until the cut faces are deeply blackened and the outer layers are scorched; turn and continue until the skins are charred on all sides and the flesh has yielded and softened throughout. The test: a skewer meets no resistance at the centre of the thickest half.
2
While the onions and habanero are still on the comal and hot, transfer the habanero to a small bowl. Slice or tear it open and stir it into the lime juice with the pinch of salt to form the marinade. The habanero's char moderates its raw heat and adds complexity to the marinade.
3
Transfer the charred onion halves immediately to a shallow dish while still hot. Pour the habanero-lime marinade over them. The test: the warm onion visibly relaxes and begins to absorb the marinade at once — the cut surfaces will deepen in colour as the liquid penetrates.
4
Allow to rest and cool to room temperature. Do not refrigerate before serving. The test: the onions are neither steaming nor cold to the touch — room temperature, at which the full balance of sweet, smoky, and floral heat is perceptible on the palate.

Quality Hierarchy
01
Reserve — White onions from a Yucatecan market variety with dense, sweet flesh; habanero sourced from Yucatán, where the floral aromatic character is most pronounced; hand-pressed lime juice used within minutes of extraction.
02
Estate — Large, firm white onions from a reliable greengrocer; fresh habanero with bright orange colour and taut skin; freshly pressed lime juice.
03
Market — Standard supermarket white onions; habanero from a well-stocked produce section; bottled lime juice only if pressed lime is unavailable.
04
House — White onions available; any habanero; lime juice from concentrate — the dry char technique and warm marination still deliver the dish's essential character at this level.

Sensory Tests
◇Touch. A skewer meets no resistance at the centre of the thickest onion half — the flesh has fully softened beneath the blackened exterior.
◇Sight. The cut surfaces of the onion deepen in colour as they absorb the habanero-lime marinade while still hot — visible penetration confirms correct temperature at marination.
◇Smell. The charred habanero releases a rounded, smoky-floral heat when broken into the lime juice — raw-chile sharpness has given way to a more complex aroma.
◇Touch. The onions are at room temperature before serving — neither steaming nor cold, the condition at which their flavour is fully expressed.
◇Where it lives or dies. The dish lives or dies at the dry comal char: oil produces fried onion; insufficient time at medium-high heat burns the surface before the interior softens; only the slow, oilless char on a flat cut face produces the caramelisation and bitter-sweet depth that defines cebollas asadas.
