Boudins de Volaille à la Richelieu

Boudins de Volaille à la Richelieu (chicken mousseline rolls filled with a sauce-bound dice of chicken, mushroom, and truffle) teach the discipline behind every delicate forcemeat: cold is structure. The paste must stay cold enough for chicken, panada, egg white, and cream to bind as one smooth emulsion. Let it warm, and it turns grainy before the pan is even hot.

The old entry assumed a saucier maintaining reduced Allemande and Périgueux sauces, stock never off the fire, little biscuit moulds by the dozen, linen for draining, and a salamander waiting over the range, though this dish itself takes its final colour in clarified butter. The home translation makes compact quantities of both sauces, shapes eight three-ounce portions on buttered parchment, poaches them in one wide saucepan, and drains them on a rack. The moulds, linen, and folded napkin are brigade scaffolding and can go. The panada-and-cream forcemeat, enclosed salpicon, gentle poach, egg and crumb, clarified-butter colouring, and sauce served apart are the dish, and they stay.

Done properly, each boudin wears a fine butter-gold crust around tender ivory mousseline, with dark flecks of truffle waiting at its centre and Périgueux sauce gleaming beside it. Before touching a pan, clear refrigerator space and chill the processor blade, bowl, chicken, panada, and cream. That is the one discipline the whole dish obeys.
