Poularde à la Chivry

Poularde à la Chivry (poached young hen with herb-green velouté) teaches the discipline of gentle heat. The chicken must poach at a tremble, but the one true thing to know before touching a pan is this: once the green butter is in the finished sauce, that sauce must never boil. A boil steals its fresh color and presses the herbs flat.

The book assumed a saucier on staff, poultry stock never off the fire, Chivry Sauce (No. 78) ready to hand, and another cook tending a Macédoine (a small-cut mixture of young vegetables). Your equivalent is one plump bird for four, the finished sauce prepared from its own entry, and one vegetable pot into which the vegetables go in stages. Linen straining and a dedicated sauce station are brigade scaffolding and remain inside the separate sauce recipe. Gentle poaching, coating the bird, and serving the macédoine apart are the dish, so all three stay. One cook, one stove, one evening.

When it is right, the flesh is tender and juicy beneath a pale herb-green sauce that gleams rather than runs, while the vegetables remain bright and distinct under their film of butter. I use the book's butter option to bind the macédoine because the velouté already supplies ample richness. Reserve a little poaching liquid before the final warming. The step that matters most is the last one: low flame, patient spoon, no bubble.
