Oysters on the Half-Shell with Grapefruit Granita

Lisa Romerein; Valerie Aikman-Smith
Yield Makes about 2 cups; 36 servings
This sparkling, vodka-laced granita has a peppery kick that sets off the briny sweetness of a good West Coast oyster. Prep Time: 15 minutes, plus 3 hours of freezing time. Notes: You can make granita up to 3 days ahead. Re-rake with fork before serving. Also, if you're serving the oysters on a buffet, serve on crushed ice with the granita in a bowl alongside, also on ice.


  • 1 cup fresh grapefruit juice (from 1 or 2 large grapefruit, preferably pink)
  • 3 tablespoons Champagne vinegar
  • 1/2 tablespoon sugar dissolved in 1/2 tbsp. hot water
  • 1/2 tablespoon vodka
  • 1/2 teaspoon finely chopped tarragon
  • 1/2 teaspoon chopped flat-leaf parsley
  • 1/2 teaspoon freshly ground black pepper
  • Rock salt or crushed ice (see Notes)
  • 3 dozen chilled small to medium oysters on the half-shell

  2. Spread rock salt on a platter. Rake and crush granita a final time into fine crystals. Set oysters in place and top each with a spoonful of granita.
