Ingredients

  • 1/4 cup red wine vinegar or aged sherry vinegar
  • 2 tablespoons balsamic vinegar
  • 1 tablespoon coarsely chopped shallot
  • 2 teaspoons Dijon mustard
  • 1/2 teaspoon salt
  • Freshly ground black pepper to taste
  • 3/4 cup mild extra-virgin olive oil

Method

  • Puree all the ingredients except the oil in a blender or food processor or with a hand-held immersion blender.
  • With the machine running, pour in the olive oil in a steady stream.
  • If you are not going to use the dressing within a few hours, store it tightly covered in the refrigerator; it will keep for several weeks.
  • Bring it to room temperature and shake or whisk it well before you dress the salad.
  • Use an herb-infused vinegar in place of the red wine vinegar.
  • Blend any of the following into the dressing: 1 to 2 tablespoons coarsely chopped English or lemon thyme, lovage, mint, oregano, marjoram, or French tarragon; 2 to 4 tablespoons coarsely chopped basil, dill, chervil, or chives; or 2 teaspoons fresh fennel seeds.
