If you don’t have time to throw together the reduction, you can use two tablespoons of white wine vinegar as a substitute.

  • ¼ cup of White Wine Vinegar
  • ¼ cup of White Wine
  • 6 whole Peppercorns
  • 1 tablespoon of Onion, diced
  • 3 Egg Yolks
  • 9 ounces of Unsalted Butter
  • ½ teaspoon of Salt
  • ¼ teaspoon of Pepper, ground
  • 2 tablespoons of Tarragon, finely chopped

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