Filets de Soles Marie Stuart

Filets de Soles Marie Stuart (sole poached in fumet, a concentrated fish stock, with lobster New-burg sauce and truffled fish quenelles) teaches the discipline of service. Each delicate element is cooked separately, then brought together hot, glossy, and dry. The one true thing to know before touching a pan is that poaching liquid cannot follow the fish onto the platter. Drain the sole and quenelles with almost comic thoroughness, or one wet underside will thin the carefully built sauce.

The old entry gives no home quantities because it assumed a saucier tending the lobster sauce, fish fumet never off the fire, and another pair of hands shaping quenelles while the sole was poached. It calls for no salamander because nothing here is gratinéed. For one cook, one stove, one evening, the honest equivalents are a finished cross-referenced sauce, a food processor instead of mortar and sieve, and one shallow pan used in sequence. Eight fillets, eight forcemeat rings, and one truffle slice on each preserve the composition for four. The extra hands were brigade scaffolding; fumet poaching, New-burg sauce, the quoit-shaped quenelles, and truffle are the dish and must stay.

On the platter, the ivory sole sits beneath a coral-cream gloss, each fillet crowned with a pale ring and a dark coin of truffle. Keep the forcemeat cold and the sauce below a simmer, but make draining the final gate: each quenelle should leave no wet mark before it touches the fish.
