Pochage à Court-Bouillon — Deep Poaching of Whole Fish

Not yet written for this entry.

Deep poaching submerges a whole fish or large cut entirely in court-bouillon — a flavoured liquid of water, white wine, aromatics, and acid — cooking it gently at 70-80°C (never a rolling boil). The technique is fundamental to the poissonnier's repertoire and underpins dozens of classical preparations. The fish is started in cold court-bouillon for whole round fish (to ensure even penetration) or lowered into hot liquid for pre-portioned cuts and flatfish. The ratio is typically 1 litre of court-bouillon per 500g of fish, with the liquid composed of roughly 60% water, 25% dry white wine, 15% aromatics (onion, carrot, celery, bouquet garni, peppercorns, and a splash of white wine vinegar). The critical principle is frémir — the liquid should barely tremble, with lazy bubbles breaking the surface every few seconds. At 80°C, fish proteins denature gently: myosin sets between 40-50°C, providing structure, while collagen begins converting to gelatin around 60°C, yielding succulence. A 1.5kg whole sea bass requires approximately 20-25 minutes from cold start to reaching 62°C at the thickest point. The fish is done when a skewer inserted at the backbone meets no resistance and the flesh along the lateral line has turned opaque. Classically, the fish is lifted on a fish kettle rack (poissonière), drained briefly, and presented on a folded napkin with the skin removed tableside. The court-bouillon itself becomes the base for the accompanying sauce — reduced, strained, and mounted with butter or enriched into a velouté.
