Suprême Sauce

Sauce suprême (the delicate cream sauce built on poultry velouté) teaches the discipline of white sauces: reduction must build body without taking colour. That is the one true thing to know before the pan comes out. A hard boil can make the cream coarse, and a neglected pan can stain the sauce, so the heat stays lively enough to reduce, never fierce enough to brown.

The old formula assumed a saucier at the pan, clear poultry stock never off the fire, and an open fire beneath a broad sauté pan. At home, a heavy saucepan supplies steady heat, a flat spatula keeps its bottom clean, and measured reduction replaces the saucier's constant eye. A salamander belongs to gratins, not this sauce, so there is nothing to imitate. Dedicated hands are brigade scaffolding; the clear stock, mushroom liquor, finished Poultry Velouté, gradual cream, fine straining, and final butter are the dish and must stay.

The source already prepares Suprême in small quantity. For the requested two-quart home batch, every amount is doubled evenly, leaving its ratios and sequence untouched. One cook, one stove, one evening. The cream must go in little by little while the sauce reduces. That measured addition decides whether the finished sauce is silken or merely thick.
