Ingredients

  • 1 pound small red boiling potatoes, scrubbed
  • 1/4 teaspoon Dijon-style mustard
  • 1 tablespoon white-wine vinegar
  • 1 1/2 teaspoons dry vermouth or dry white wine
  • 2 tablespoons olive oil
  • 1/4 cup minced fresh dill

Method

  • Cut the potatoes lengthwise into fourths and in a steamer set over boiling water steam them, covered, for 7 to 10 minutes, or until they are just tender.
  • In a bowl whisk together the mustard, the vinegar, the vermouth, and salt to taste, add the oil in a stream, whisking, and whisk the dressing until it is emulsified.
  • Add the potatoes while they are still warm to the dressing and toss them gently with the dressing, the dill, and pepper to taste until they are coated well.
  • Let the potato mixture stand, tossing it occasionally, for 30 minutes and serve it at room temperature.
  • The potato mixture may be made 1 day in advance and kept covered and chilled.
  • Let the potato mixture return to room temperature before serving.
