Ingredients

  • 2 large or 4 small lobster tails
  • 2 tablespoons butter
  • 1 large garlic clove minced
  • 1/2 cup heavy whipping cream
  • 1/4 cup white wine pinto gris or chardonnay
  • 6.5 ounce can of clams with juice reserved
  • 1 teaspoon cornstarch
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon fresh ground pepper
  • 1 tablespoon minced fresh parsley plus more for garnish
  • 1/2 cup shredded gruyere cheese

Instructions

  • Remove from the grill and remove the lobster meat from the shell.

Notes

STORAGE: Store leftover lobster in an airtight container in the refrigerator up to 2 days.
