Ingredients

  • 2 to 3 cups rock or coarse salt
  • 2 dozen oysters, shucked, liquor and bottom shells reserved separately
  • 1 cup heavy cream
  • 1 cup dry champagne or sparkling wine
  • 3 large shallots, minced (about 1/2 cup)
  • 1/4 cup white-wine vinegar
  • 2 1/2 sticks (1 1/4 cups) cold unsalted butter, cut into pieces
  • Coarse salt and freshly ground white pepper
  • 1 pound fresh or 2 10-ounce packages frozen spinach, thawed
  • Snipped fresh chives, for garnish

Method

  • Pour the salt into a rimmed baking sheet.
  • Nestle the oyster shells in the salt; set aside.
  • Bring the cream to a boil.
  • Reduce to a simmer; cook until reduced by half.
  • Remove from heat.
  • Meanwhile, place the champagne, shallots, and vinegar in another small saucepan.
  • Bring to a simmer, and cook until the liquid is almost evaporated.
  • Add the reduced cream, and cook for 1 minute.
  • Remove pan from heat, and whisk in butter, 1 piece at a time, adding each piece before the previous one melts completely.
  • (The sauce should not get hot enough to liquefy.)
  • Add 1/2 cup oyster liquor; season with salt and pepper.
  • Keep warm.
  • If using fresh spinach, rinse it thoroughly several times, and place in a saucepan with just the water that clings to the leaves.
  • Cover the pan, and cook the spinach until bright green and just tender, about 2 minutes.
  • Drain well, and roughly chop.
  • (Squeeze excess moisture from thawed frozen spinach.)
  • Preheat the broiler with the rack set 5 inches from the heat source.
  • Divide the spinach equally among the shells.
  • Top with the shucked oysters.
  • Spoon on enough sauce to cover the oysters, about 1 tablespoon per shell.
  • Place under the broiler until the sauce bubbles and the edges of the oysters start to curl, about 1 minute.
  • Garnish with chives, and serve.
