Coulis de Volaille, otherwise à la Reine

Coulis de Volaille, otherwise à la Reine (velvet chicken coulis), teaches the gentlest binding in the classical soup pot: once the liaison (egg-yolk binding) enters, the soup must never boil. That is the one true thing to know before touching the pan. Everything before it builds body; that final restraint preserves the velvet.

The grand kitchen assumed a saucier at the pot, white consommé never off the fire, a mortar for pounding the fowl, and a tammy broad enough to handle service. A salamander has no part in this dish. At home, a prepared batch of consommé, a countertop blender, and a fine-mesh sieve do the work for one cook, one stove, one evening. The mortar and service-sized handling were brigade scaffolding and can go. The pounding, two careful strainings, and final liaison are the dish and must stay. The source formula's three-pound bird already settles neatly into a dinner-party pot of about two quarts, so its proportions are kept intact.

When à la Reine is right, it pours in an ivory ribbon, tastes deeply of chicken without heaviness, and carries a quiet gleam from the butter. Keep the pot gentle after tempering the yolks, then take it completely off the heat before the butter goes in. That final minute decides everything.
