Tripes à la Mode de Caen

Tripes à la Mode de Caen is Normandy's most celebrated offal dish — a 12-hour slow cook of the four stomachs of a beef animal that transforms this most challenging of ingredients into a dish of extraordinary tenderness and depth. The canonical recipe, codified by the Confrérie de la Tripaille de Caen (founded 1952), requires all four stomachs: the rumen (panse), reticulum (bonnet/honeycomb), omasum (feuillet/book tripe), and abomasum (caillette). Each is prepared differently: the panse and bonnet are cut into 5cm squares, the feuillet into strips, and the caillette left in larger pieces. The tripe is layered in a tall, narrow earthenware pot (tripière) with sliced onions, leeks, carrots, a split calf's foot (for gelatin), bouquet garni (thyme, bay, parsley), garlic, whole black peppercorns, and cloves. The critical detail: the tripe is moistened with dry cider (not wine — this is Normandy), approximately 1 liter per kilo of tripe. A piece of beef suet seals the top, and a flour-and-water paste (lut) seals the lid hermetically. The tripière goes into the oven at 120°C for a minimum of 10 hours, ideally 12 — during which time the collagen converts entirely to gelatin, the calf’s foot dissolves into the sauce, and the cider reduces to a golden, silky, intensely savory liquor. The tripes should be so tender they can be cut with a spoon, swimming in a sauce that gels when cool. A generous splash of Calvados is added just before serving. The dish is traditionally eaten on Saturday mornings at the marché — triperies in Caen and across Normandy serve it steaming hot from the tripière at dawn to early-rising market-goers.
