Sole Nantua

Sole Nantua (sole poached with crayfish sauce) teaches one true thing before you touch the pan: gentle heat protects delicacy. The fumet must barely tremble beneath the fish, and the crayfish butter must enter the sauce away from a boil. Rush either one and the sole tightens while the Sauce Nantua loses its gloss.

The original entry assumed a saucier on staff, fish fumet and mushroom cooking liquor already waiting, crayfish butter warm at the pass, and enough hands to poach, drain, sauce, and garnish at once. Your home equivalent is one small saucepan used in sequence, one wide lidded pan, 95 ml of fumet in place of the book's one-sixth pint, and four fillets sharing its twelve crayfish tails. There is no use for a salamander here because this dish is nappé, cloaked with sauce, not browned. The standing pantry and holding station were brigade scaffolding and can go; the gentle fumet poach, the Sauce Nantua, the twelve tails, and the dark truffle line are the dish and must stay.

When it lands on the table, the sole should be pearly beneath a rosy, satin sauce, with coral tails circling it and black truffle marking the center. One cook, one stove, one evening. When you reach the poach, watch the surface rather than the clock: one or two quiet bubbles at the edge, never a boil.
