Aiguillettes de Rouennais à la Bigarrade

Aiguillettes de Rouennais à la Bigarrade (lengthwise slices of Rouen duck breast with bitter-orange sauce) teaches control, not complication. Before you touch the pan, know the one true thing: the duck must remain rosy. The sauce can wait, the platter can wait, but another five minutes of cooking cannot be taken back.

The original expected a whole Rouennais duckling, a saucier beside the cook, and brown veal gravy from a stockpot never off the fire. Your honest home equivalent is a meaty duck crown, which preserves the breast cookery without leaving one cook to manage underdone legs, plus good unsalted veal demi-glace diluted to a light gravy. The brigade's elaborate wrapping of large poultry and its service choreography are scaffolding here. The twenty-minute poëling, the extraction of the liquor before degreasing, the lengthwise slicing, and the bitter-orange caramel are the dish, and they stay. One cook, one stove, one evening.

When it is right, the aiguillettes lie in overlapping fans, their centres warm and pink beneath burnished skin, while the bigarrade runs clear and amber around them with just enough bitterness to pull against the duck's richness. The step that decides everything is simple: stop the poëling at twenty minutes and transfer the meat to a merely lukewarm platter, never a hot one.
