Caneton Rouennais au Champagne

Caneton Rouennais au Champagne (Rouen duckling with Champagne sauce) teaches an unfashionable but exact truth: don't degrease the poëling-liquor too soon. The butter has carried the savor of the duck and its aromatics through the cooking. Let the Champagne reduce in that liquor, then give the thickened veal stock ten minutes with it before lifting away the fat. Skim first and you throw out the bridge between bird and sauce.

The original expected the duckling to arrive from Poëlings (No. 250), a saucier on staff, thickened veal stock never off the fire, and muslin ready for the final strain. Your kitchen needs one cooking vessel, one 4½-pound duckling prepared through the linked component, good reduced veal stock, and damp cheesecloth set inside a fine sieve. Saint Marceaux becomes any dry brut Champagne because the house named on the bottle is not the technique. The book already works by the duckling, so its honest home scale is four servings, and the Champagne-to-stock ratio remains exactly three to one. The brigade handoff is scaffolding and goes. The poëling and reduction stay. A salamander had no work here, so one is not invented.

Finished properly, the duckling wears a butter-bronze skin while the sauce runs clear, glossy, and amber-brown from its warm sauceboat. It tastes first of concentrated duck, then of Champagne's acidity, with veal stock supplying quiet depth underneath. Watch the Champagne rather than the clock: it must lose its raw wine smell and reduce to one-third without scorching. That reduction is the step that decides everything.
