In Practice
Place whole vegetable (eggplant, pepper, tomato) directly on an open gas-stove flame OR on a hot charcoal grill. Use tongs to turn every 2-3 minutes so all sides char evenly. Eggplant: 15-25 minutes until skin is completely blackened and the vegetable collapses (poked easily). Pepper: 8-12 min. Tomato: 4-6 min. After charring, transfer to a covered bowl or paper bag for 10 minutes — the trapped steam loosens the skin. Peel off the blackened skin (do NOT wash; you'd lose the smoke). Reserve the soft smoky flesh for the dish.
Background
Char-roasting predates indoor cooking — outdoor wood fires were the original 'oven'. Documented in Bronze-Age Mediterranean cooking, Mesoamerican comal-charring of chilies and tomatoes, and Levantine vegetable cooking continuously since antiquity. The modern restaurant version uses gas burners or salamander grills; the home version uses gas-stove burners (set directly on the flame) or a backyard grill.
How It Works
Direct flame contact at 700-900°C carbonizes the outer cell layer to elemental carbon (the 'char'), while the steam trapped inside the vegetable's flesh cooks the interior to ~100°C — soft, sweet, and smoke-absorbed. The Maillard reaction is short-circuited (you skip past browning into carbonization), but pyrolysis of the skin's natural compounds generates smoke-aromatic phenols and guaiacol that penetrate the flesh.

Through Time
From Bronze-Age open-fire cookery through medieval Levantine kitchens to the 20th-century rediscovery by Yotam Ottolenghi, Sami Tamimi, and modern Israeli/Levantine cookbook authors. Mexican chile-roasting on the comal is the New World cousin. American 'fire-roasted' canned tomatoes are the industrial echo.
Related cooking knowledge
Sister to grilling (but more intense), tandoori (vertical-shaft variant), pit roasting (sealed-chamber slow variant). The closest cousin is Mexican comal toasting of chilies (similar pyrolysis-of-skin mechanism on a flat hot griddle).
