Coq au vin is a classic French dish of chicken braised in red wine with bacon, mushrooms, and small onions. Traditionally made with a mature rooster needing long cooking, modern versions use chicken pieces simmered until tender in a Burgundy-style wine enriched with stock. The wine’s acidity and tannins mellow into a rich sauce, thickened lightly and finished with beurre manié. Like boeuf bourguignon it demonstrates how slow braising transforms humble ingredients, with collagen becoming gelatin and flavours melding. It is rustic French cooking at its most celebrated, best served with crusty bread or buttered noodles.
