Ingredients

  • 2 tablespoons sherry vinegar
  • 1 1/2 teaspoons aged red-wine vinegar
  • 1/2 teaspoon Dijon mustard
  • 1 tablespoon black-truffle juice, or more, if necessary
  • 4 tablespoons black-truffle oil
  • Kosher salt and freshly ground black pepper to taste
  • 1 pound fresh porcini mushrooms
  • 1 tablespoon unsalted butter
  • 1 small shallot, peeled and minced
  • 1/4 pound (about 8 cups) mixed baby lettuces (avoid bitter greens like arugula), washed and dried
  • 2 tablespoons minced chives

Method

  • To make the vinaigrette, whisk together the vinegars, mustard and truffle juice in a small bowl.
  • Slowly whisk in the truffle oil.
  • (You should obtain an emulsified vinaigrette thick enough to coat the back of a spoon; if too thick, whisk in more truffle juice or water.)
  • Season to taste with salt and pepper.
  • To make the salad, clean dirt from the mushrooms and, depending on their size, either slice them or cut into julienne.
  • Set aside.
  • In a skillet over medium heat, melt the butter and cook until it just begins to turn brown.
  • Add the mushrooms and cook, stirring, only until thoroughly warm and slightly tender.
  • Add the shallots and remove from heat.
  • Transfer the mushrooms to a mixing bowl and toss with half the vinaigrette and half the chives.
  • Season with salt and pepper.
  • In another bowl, toss the greens with the remaining vinaigrette and chives.
  • Divide among 4 plates and top with mushrooms.
  • Serve immediately.
