White Chaud-Froid Sauce

Sauce chaud-froid blanche (white cold coating sauce) teaches the discipline of judging a sauce at the temperature in which it will be used. Hot, it must look too loose. Cold, its poultry jelly gives it enough body to veil a chilled piece in smooth ivory while remaining fluid enough for dipping. The one true thing to know before touching the pan is this: the sauce is finished during cooling, not at the boil.

The old formula assumed a saucier who could stir without interruption, velouté and white poultry jelly waiting from a stockpot never off the fire, an open flame, and a tammy cloth close at hand. A salamander has no work here. At home, one heavy saucepan replaces the fire, a fine sieve replaces the tammy, and a cold-water bath lets one cook control the set. The brigade's extra hands and repeated pans were scaffolding and can go. The one-third reduction, gradual addition of cream, fine straining, and stirring through cooling are the dish and must stay.

This batch keeps the original proportion exactly: one part velouté, three-quarters part poultry jelly, and one-half part cream. It makes enough for a generous dinner-party platter, all in one pan. One cook, one stove, one evening. The step that matters most is the cooling: stir until the sauce is cold enough to coat, then test it on a chilled spoon before the first piece goes in.
