Volaille de Bresse en Vessie

Poulet en vessie — chicken cooked inside a pig’s bladder — is the supreme expression of Lyonnais haute cuisine, forever associated with Mère Filloux and her successor Eugenie Brazier, the only chef to hold six Michelin stars simultaneously. The technique is a masterclass in sealed-environment cooking that predates sous vide by centuries. A Bresse chicken (AOC, corn-fed, free-range for minimum 4 months, finished in épinette for 2 weeks) is truffled 24 hours in advance: slices of fresh Périgord truffle are slid under the skin of the breast and thighs, and the cavity is stuffed with additional truffle pieces, foie gras, and a mirepoix sautéed in butter. The prepared bird is then placed inside a thoroughly cleaned and soaked pig’s bladder (vessie de porc), which is tied tightly with butcher’s string, leaving a small pocket of air. The bladder is poached in a rich chicken stock fortified with aromatics (carrots, leeks, celery, bouquet garni) at exactly 82-85°C for 1 hour 45 minutes. The bladder inflates dramatically during cooking, puffing to the size of a football as the steam and juices are trapped inside. This sealed environment achieves several things simultaneously: the chicken steams in its own concentrated juices and truffle essence, the breast meat (normally prone to overcooking) stays supremely moist, and the truffle aroma permeates every fiber of the flesh. The bladder is brought to the table intact and ceremonially cut open with scissors, releasing an intoxicating cloud of truffle-perfumed steam. The juices collected inside the bladder are reduced with crème fraîche to make the sauce. This dish cannot be simplified or shortcutted — it requires genuine Bresse poultry, fresh truffle, and the bladder itself.
