1 large cucumber
1/2 cup white-wine vinegar
3 tablespoons sugar
1 tablespoon finely chopped fresh mint leaves
1 tablespoon finely chopped fresh parsley leaves
1/2 teaspoon salt
1/4 teaspoon freshly ground black pepper
Cut cucumber crosswise into very thin slices (preferably using a manual slicer). In a bowl whisk together remaining ingredients until sugar is dissolved and add cucumber, tossing to coat. Marinate cucumbers, covered and chilled, stirring occasionally, 4 hours.
