Quenelle de Brochet Sauce Nantua

While quenelles have been covered elsewhere as a technique, the specific pairing of Quenelle de Brochet with Sauce Nantua—Lyon’s most celebrated dish—demands its own entry as a completed composition. The quenelle itself is a pike mousse of extreme delicacy: fresh pike flesh (dégorged in cold milk for 2 hours to whiten and purify), panade (flour, butter, milk, and eggs cooked to a thick paste), butter, eggs, and cream are processed to an impossibly light, cloud-like farce, shaped into elongated ovals using two large spoons, and poached in gently simmering salted water for 12-15 minutes until they puff to nearly double their original size. The Sauce Nantua that accompanies them is a Béchamel-based sauce enriched with crayfish butter (beurre d’écrevisse)—made by pounding crayfish shells with butter, gently heating to extract the flavour and brilliant orange-red colour, then straining through fine muslin. The sauce is finished with cream, a splash of cognac, and the reserved crayfish tails for garnish. The assembled dish presents two or three quenelles in a pool of coral-coloured Nantua sauce, garnished with whole crayfish tails and sometimes glazed briefly under the salamander. The quenelle should quiver on the spoon, dissolving on the tongue into a wave of delicate pike flavour, while the sauce provides the sweet, shellfish richness that elevates the combination into one of French cuisine’s greatest partnerships. Paul Bocuse made this dish his signature at the restaurant in Collonges-au-Mont-d’Or, and it remains the barometer by which every serious Lyonnais restaurant is judged.
