Scallops with Mushrooms in White-Wine Sauce

Preparation

1. Step 1

   Preheat oven to 350°F.

   Step 2

   Toast bread crumbs on a baking sheet in middle of oven until pale golden, 6 to 8 minutes, then toss with cheese.

   Step 3

   Simmer wine, water, onion, bay leaf, salt, and pepper in a 2 1/2- to 3-quart heavy saucepan, uncovered, 5 minutes, then add scallops and simmer, uncovered, stirring occasionally, until just cooked through, 2 to 3 minutes. Transfer scallops to a platter with a slotted spoon to cool, returning any onions to pan, then boil cooking liquid until reduced to about 1 cup, 8 to 10 minutes. Pour cooking liquid through a sieve into a bowl.

   Step 4

   Cook mushrooms in 2 tablespoons butter in a 10- to 12-inch heavy skillet over moderate heat, stirring occasionally, until most of liquid mushrooms give off is evaporated, about 5 minutes. Season with salt and pepper.

   Step 5

   Whisk together cream and yolk in a heatproof bowl. Melt 2 tablespoons butter in cleaned 2 1/2- to 3-quart saucepan over moderately low heat, then add flour and cook roux, whisking, 2 minutes. Remove pan from heat and add reduced cooking liquid in a stream, whisking constantly. Return pan to heat and simmer, whisking, 1 minute. Pour sauce in a slow stream into cream mixture, whisking constantly, then pour sauce back into pan and simmer, whisking, 1 minute. Remove from heat and season with salt and pepper.

   Step 6

   Preheat broiler.

   Step 7

   Stir scallops and mushrooms into sauce, then divide among scallop shells or ramekins and sprinkle with bread crumb mixture. If using shells, spread kosher salt evenly in a large shallow baking pan, then nestle shells in salt. Dot scallops with remaining 2 tablespoons butter, then broil about 4 inches from heat until golden, about 2 minutes.

   Step 8

   Sprinkle with parsley.
