Filets de Soles Pompadour

Filets de Soles Pompadour (Pompadour sole fillets) teaches coordination. The fish must reach the platter bronzed and moist just as the Béarnaise tomatée (tomato-tinted Béarnaise) becomes warm, glossy, and firm enough to hold a cord. Know this before touching a pan: the sauce is not meant to puddle. It must stand.

The original preparation assumed a saucier minding the emulsion, a stockpot never off the fire supplying meat glaze, a salamander for fierce overhead heat, and another pair of hands turning the potatoes. At home, a bowl over barely warm water replaces the saucier, good unsalted demi-glace reduced by half supplies the spoonful of meat glaze, and the ordinary broiler does the salamander's work. Eight fillets serve four, and the Pommes de Terre Château (No. 2208) arrive as their own finished preparation. That is the brigade scaled down honestly: one cook, one stove, one evening.

The holding pans and extra hands were scaffolding, so they can go. The buttered crumbs, grilled sole, firm Béarnaise tomatée, potatoes, and truffle are the dish, so every one stays. Whisk the yolks to a true ribbon before the butter enters; that sabayon is the step that makes the Béarnaise stand.
