Sole Bonne Femme

Sole Bonne Femme (the good wife's sole) teaches the clean separation between cooking a fish and finishing its sauce. The sole poaches gently over shallot, parsley, mushroom, white wine, and fumet, then leaves the dish before the cooking liquor is reduced. That is the one true thing to know before touching a pan: reduce around the fish and you'll dry it; reduce after lifting it out and you concentrate every drop without stealing its tenderness.

The original recipe assumed a saucier on staff, fish stock never off the fire, prepared velouté within reach, and a salamander fierce enough to glaze the sauce in moments. At home, prepared fish fumet and fish velouté stand ready beside one gratin dish, one small saucepan, and a thoroughly heated broiler. Sole fillets replace the large service fish so four portions cook evenly and lift cleanly from a home dish. The separate sauce station was brigade scaffolding and can go; the gentle poach, rapid reduction, velouté liaison, butter finish, and fierce glaze are the dish, so every one stays. One cook, one stove, one evening.

You are after pearl-white fish beneath an ivory sauce, with minced mushrooms still distinct and a pale gold gloss across the highest points. Keep the poaching liquor at a bare tremble, never a boil, and have the broiler ready before mounting the sauce with butter. The step that decides the dish is the rapid reduction after the sole comes out.
