Poularde Isabelle de France

Poularde Isabelle de France (stuffed young hen poached in Chablis) teaches one uncompromising lesson: the poach is also the sauce, so the liquid must barely tremble from the moment the bird enters. Boil it and you tighten the flesh, cloud the cooking liquor, and weaken the sauce suprême before it has begun. Gentle heat is the dish.

The original assumed a saucier at the next station, white stock never off the fire, crayfish being shelled by another pair of hands, and a formal platter raised on a cushion. At home, good frozen cooked crayfish tails remove the shelling station, a snug pot makes one bottle of Chablis sufficient, and the sauce is finished while the bird rests. A four-serving poularde is the natural home scale, so the specified eighteen tails, two ounces of sliced truffle, and full bottle of Chablis remain attached to the bird; only the surrounding whole truffles become four, one for each guest. One cook, one stove, one evening.

The old cushion is service scaffolding and can go. The compact rizotto, truffle, crayfish, wine poach, sauce suprême, and whole truffles on butter-fried croûtons are the dish, and every one stays. When it reaches the table, the bird should wear an ivory gloss, the stuffing should be rich but distinct, and each black truffle should sit in its golden croûton catching the Champagne glaze. Watch the poaching liquid, not the clock: hold it below a simmer and everything else follows.
