- 6 hard-cooked large eggs
- 3 tablespoons sour cream
- 1 teaspoon Dijon mustard
- 1/2 teaspoon white-wine vinegar
- 1/2 cup packed watercress sprigs, chopped fine
- 3 tablespoons minced radish (about 3 large)
- 3 tablespoons minced celery (about 1 rib)
- Garnish: finely chopped radish
- Cut a paper-thin slice off both ends of eggs and halve eggs crosswise. Force yolks through a sieve into a bowl (or mash with a fork) and stir in remaining ingredients and salt and pepper to taste. Transfer filling to a pastry bag fitted with a large decorative tip and pipe into whites, mounding it. The stuffed eggs may be made 6 hours ahead and chilled, covered.
- Just before serving, garnish eggs.
