Ingredients

  • 4 tablespoons (1/2 stick) unsalted butter, softened, plus more for the pan
  • 1 cup champagne vinegar
  • 2 tablespoons minced shallots
  • 1/3 cup heavy cream
  • Kosher salt
  • Cayenne pepper
  • 20 large (16- to 20-count) shrimp, shelled and deveined
  • 12 ounces mixed greens (about 8 cups)
  • 1/2 cup peeled, diced fresh tomatoes
  • 2 avocados, halved, pitted, peeled, and thinly sliced
  • 4 large white mushroom caps, thinly sliced
  • House Dressing (page 245)
  • 2 tablespoons snipped chives, for garnish

Method

  • Arrange an oven rack 4 inches from the broiler heat source.
  • Preheat the broiler.
  • Generously butter a rimmed baking sheet.
  • In a small saucepan, combine the vinegar and shallots.
  • Boil over high heat, stirring occasionally, until the liquid has almost completely evaporated and the shallots are glazed, 12 to 15 minutes.
  • Stir in the cream and continue boiling until reduced by half, about 2 minutes.
  • Reduce the heat to low and whisk in the butter, a little at a time, until well incorporated.
  • Season to taste with salt and cayenne.
  • Meanwhile, butterfly the shrimp by cutting each in half along its vein, slicing all the way through the curved middle, but keeping the stubby ends connected.
  • Open the butterflied shrimp (theyll resemble hearts) and arrange in the prepared pan in a single layer.
  • Season with salt and cayenne, then splash a little water over the shrimp.
  • Broil until the shrimp just become opaque, about 3 minutes.
  • Divide the greens among serving dishes.
  • Arrange the tomatoes and avocados over the greens, then scatter the mushrooms all around.
  • Spoon the dressing all over.
  • Arrange the shrimp around the center and spoon the beurre blanc over the shrimp.
  • Garnish with chives.
  • To keep shrimp moist and juicy while getting lightly browned in the broiler, I add a splash of water to the pan.
  • Think of it as steam-broiling.
