  • 1/4 cup white wine vinegar
  • 1/4 cup white wine
  • 6 peppercorns
  • 1 tablespoon onion diced
  • 3 egg yolks
  • 9 ounces unsalted butter
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper ground
  • 2 tablespoons fresh tarragon finely chopped


  • Place a small saucepan over medium heat, add the vinegar, wine, peppercorns, and onion. Reduce until 2-3 tablespoons of liquid remain. 
  • Strain out the onion and peppercorns and pour the liquid into a heatproof bowl. Add the egg yolks.
  • Melt the butter until the milk fat (white liquid) has separated from the yellow butter. Set aside.
  • Place the bowl over a saucepan of simmering water and start whisking.
  • Continue to whisk until the mixture is thick and foamy and creates thick ribbons when the whisk is lifted.
  • Remove the bowl from the heat and slowly pour in the hot butter while whisking, ensuring that the milk fat is left behind. This step is similar to making mayonnaise - if you add the butter too quickly the sauce will split.
  • Whisk in the salt, pepper, and tarragon.
  • Serve immediately or keep warm until needed.
