Sole Montgolfier

Sole Montgolfier (white-wine-poached sole with lobster, mushroom, black truffle, and pale puff-pastry palmettes) teaches coordination. The fish is delicate, the sauce is built, and the pastry waits for neither; the luxury lies less in complication than in bringing all three to the platter at their best. One true thing before you touch a pan: the poaching liquid must barely tremble. A boil tightens sole before the sauce is ready.

The original formula assumed a saucier with sauce au vin blanc (white-wine sauce) at hand, mushroom cooking liquor and fish stock never off the fire, a pastry station cutting palmettes, and a service line with a salamander. The salamander has no useful work here because the pastry must remain pale. At home, purchased all-butter puff pastry replaces the pastry station, a small blond roux and good fish stock build only the sauce needed tonight, and one shallow pan supplies the reduced cooking liquor. Four skinless fillets cook evenly in that pan. The brigade scaffolding goes; the equal measure of wine and mushroom liquor, the fine julienne, the pale palmettes, and the coating of sauce stay. One cook, one stove, one evening.

Bake the palmettes first, make the sauce base second, then poach the sole and finish the sauce with its reduced liquor. The sauce can wait a few minutes and can be rescued; the sole cannot be uncooked. The step that decides Sole Montgolfier is the gentle poach, so watch the surface, not the clock.
