Ingredients

2 cups water

1 cup dry white wine, such as Sauvignon Blanc

2 teaspoons coarse salt

1 dried bay leaf

1 pound medium shrimp, peeled and deveined, tails removed

2 tablespoons fresh lemon juice

1 tablespoon white-wine vinegar

1/4 cup extra-virgin olive oil

1/4 cup plus 2 tablespoons creme fraiche

2 tablespoons finely chopped shallot

2 tablespoons minced fresh chives

2 small Belgian endives

Thin crackers, for serving

Preparation

Bring water, wine, 1 teaspoon salt, and the bay leaf to a boil in a medium saucepan. Reduce heat, and simmer for 5 minutes. Add half the shrimp, and cook until opaque, about 1 minute. Using a slotted spoon, transfer shrimp to a plate, and let cool. Repeat with remaining shrimp. Cut into 1/2-inch pieces.

Whisk together lemon juice, vinegar, and remaining 1 teaspoon salt in a medium bowl. Pour in oil in a slow, steady stream, whisking until emulsified. Whisk in creme fraiche. Fold in shallot, chives, and shrimp. Cover with plastic wrap, and refrigerate for at least 30 minutes (and up to 4 hours). Just before serving, separate endive leaves, and thinly slice crosswise. Fold endive into shrimp mixture. Serve on crackers.
