Ingredients

  • 3 egg yolks
  • 1/4 cup water
  • 3 tablespoons white wine or chicken broth
  • 2 tablespoons tarragon vinegar
  • 2 teaspoons minced shallot
  • 2-1/2 teaspoons minced fresh tarragon, divided
  • 8 whole peppercorns, crushed
  • 1/2 cup cold butter

Method

  • In a small heavy saucepan, whisk the egg yolks and water. Cook and stir over low heat or simmering water until mixture bubbles around edges and reaches 160°, about 20 minutes.
  • Meanwhile, in a small saucepan, combine the wine or broth, vinegar, shallot, 1-1/2 teaspoons tarragon and peppercorns. Bring to a boil. Reduce heat; simmer, uncovered, for 10 minutes or until reduced to 2 tablespoons. Strain and set liquid aside.
  • Cut cold butter into eight pieces; add to egg yolk mixture, one piece at a time, stirring after each addition until melted. Stir reserved liquid and remaining tarragon into prepared sauce. Serve immediately.
