Quenelles de brochet (pike dumplings) in sauce Nantua (crayfish butter sauce) is the other pillar of Lyonnaise fine dining — Mère Brazier's eternal menu companion to poularde demi-deuil. Pike flesh is pounded to a paste (panade), enriched with eggs, butter, and cream, shaped into oval dumplings, and poached in stock. They are then napped in sauce Nantua — a béchamel enriched with crayfish butter (made by pounding crayfish shells with butter to extract the carotenoid-rich fat) and finished with cream. The result is impossibly light, ethereally smooth, and deeply flavoured.
- **The panade must be worked to absolute smoothness.** The pike flesh is pounded (traditionally in a mortar, now in a food processor) with choux paste or bread panade, then passed through a fine sieve (tamis). Any grain, any fibre, any lump destroys the quenelle's defining quality: a texture that dissolves on the tongue. - **Cold is your friend.** The mixture must stay cold throughout. Warm pike paste becomes slack and won't hold its shape. Work on ice. - **Sauce Nantua is the crayfish shell's gift.** The shells (not the tail meat — which is served whole alongside) are pounded with butter. The butter extracts the red-orange carotenoid pigments and the crustacean flavour from the chitin. This compound butter, whisked into a béchamel, produces a sauce that is simultaneously rich, crustacean-flavoured, and salmon-pink.
