Ingredients

  • 2 (1 1/2-lb) live lobsters
  • 1/2 stick (1/4 cup) unsalted butter
  • 1/4 lb mushrooms, trimmed and thinly sliced
  • 1/2 teaspoon paprika
  • 1/8 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 tablespoons medium-dry Sherry
  • 1 cup heavy cream, scalded
  • 2 large egg yolks

Method

  • Plunge lobsters headfirst into an 8-quart pot of boiling salted water*.
  • Loosely cover pot and cook lobsters over moderately high heat 9 minutes from time they enter water, then transfer with tongs to sink to cool.
  • When lobsters are cool enough to handle, twist off claws and crack them, then remove meat.
  • Halve lobsters lengthwise with kitchen shears, beginning from tail end, then remove tail meat, reserving shells.
  • Cut all lobster meat into 1/4-inch pieces.
  • Discard any remaining lobster innards, then rinse and dry shells.
  • Heat butter in a 2-quart heavy saucepan over moderate heat until foam subsides, then cook mushrooms, stirring, until liquid that mushrooms give off is evaporated and they begin to brown, about 5 minutes.
  • Add lobster meat, paprika, salt, and pepper and reduce heat to low.
  • Cook, shaking pan gently, 1 minute.
  • Add 1 tablespoon Sherry and 1/2 cup hot cream and simmer 5 minutes.
  • Whisk together yolks and remaining tablespoon Sherry in a small bowl.
  • Slowly pour remaining 1/2 cup hot cream into yolks, whisking constantly, and transfer to a small heavy saucepan.
  • Cook custard over very low heat, whisking constantly, until it is slightly thickened and registers 160F on an instant-read thermometer.
  • Add custard to lobster mixture, stirring gently.
  • Preheat broiler.
  • Arrange lobster shells, cut sides up, in a shallow baking pan and spoon lobster with some of sauce into shells.
  • Broil lobsters 6 inches from heat until golden brown, 4 to 5 minutes.
  • Serve remaining sauce on the side.
  • When salting water for cooking, use 1 tablespoon salt for every 4 quarts water.
