Filets de Soles Bercy

Filets de Soles Bercy (sole fillets with shallot, white wine, and fish fumet) teaches one true thing: baste, don't boil. The fillets sit on a bed of shallots in equal measures of wine and fumet while butter carries that fragrant liquor over the fish. Fumet means a concentrated fish essence, and here it supplies the foundation beneath an otherwise spare dish.

The classical entry assumed a saucier standing by to baste, fish stock never off the fire, and a salamander ready for the final glaze. The home equivalent is three tablespoons of finished fumet, a large spoon, a snug broiler-safe dish, and the top element of an ordinary oven. The unnamed brigade service becomes eight small fillets for four people, while the book's proportions remain intact. Its alternate saucepan reduction is scaffolding and can go tonight; the shallot bed, equal wine and fumet, repeated basting, and last-minute glaze are the dish and must stay. One cook, one stove, one evening.

The finished sole should be tender and pearly beneath a butter-gold gloss, with lemon brightening the sauce only at the end. Watch the cooking liquor rather than the clock: it must barely tremble while you spoon it over the fillets. That is the step that decides Filets de Soles Bercy.
