Poularde aux Champignons à Brun

Poularde aux Champignons à Brun (butter-roasted pullet with mushrooms and Madeira demi-glace) teaches the difference between roasting in fat and braising in liquid. The poêlé, a covered butter roast, must remain unmoistened while the bird cooks. Add stock too early and you wash away the concentrated poultry savour that this sauce exists to collect.

The original assumed a saucier on staff, mushroom essence and Madeira demi-glace ready, a stock never off the fire, and enough hands to groove twenty mushroom caps while the bird cooked through Poëlings (No. 250). At home, a snug lidded casserole replaces the deep poëling vessel, a fine-mesh sieve replaces cloth straining, mushroom stems provide the essence, and a good prepared veal demi-glace supplies the honest foundation. The separate saucier and brigade quantities are scaffolding and can go. The dry cook, pan swill, twenty caps, and full two ounces of finishing butter must stay. No salamander is required; the poêlé gives the bird its own colour. One cook, one stove, one evening.

The pan swill and the final monter au beurre (finishing the sauce with cold butter) are the dish. If the reduction tightens, water loosens it; if the butter splits, begin again with cool water and rebuild it spoon by spoon. Ça se rattrape. The last step matters most: after the cold butter enters, the sauce never boils.
