Turbotin Mirabeau

Turbotin Mirabeau (small turbot striped with two sauces) teaches precision in service: two sauces can share one fish only when they have exactly the same body. Bring both to a nappant consistency, thick enough to coat a spoon in an even veil. Too loose and the bands bleed together; too stiff and they sit on the fish like paste. The pattern isn't decoration laid over the dish. It distributes white wine, red wine, anchovy, truffle, and tarragon from one end of the fish to the other.

The original assumed a whole chicken-turbot, a fish poacher with a lifting grid, a saucier holding two finished sauces, and stock never off the fire. At home, a snug roasting pan, a parchment sling, two small saucepans, and good fish stock do the same work for four. The fitted grid and separate sauce station were brigade scaffolding and can go. The Sauterne court-bouillon, the distinct sauce vin blanc and sauce Genevoise, and their alternating bands are the dish and must stay. A salamander contributes nothing here because the fish is poached and coated, never browned. One cook, one stove, one evening.

When it is right, the turbot remains pearly and succulent beneath ribbons of ivory and wine-dark brown, with salty anchovy marking every seam and black truffle answering the green tarragon. Make both sauces before the fish enters its liquor, then match their consistency before the first spoonful touches the platter. That is the step that matters most.
