Ingredients

  • 1 c butter
  • 3 T finely diced shallots
  • 1/4 c white wine or champagne vinegar
  • 1/4 c white wine I used Chardonnay
  • 3 large egg YOLKS
  • 1 T fresh lemon juice about half of a lemon
  • 3 T finely chopped fresh tarragon
  • 1/4-1/2 t Kosher salt
  • 1/4 t freshly cracked pepper

Instructions

  • Slightly saute shallots in 1 tablespoon of the butter.
  • Add vinegar and wine on medium-low for 3 minutes. Reduce heat to low and continue to reduce for about 5 more minutes or until most of the liquid has evaporated.
  • In a separate pan, melt remaining butter until foamy. Pour into a measuring cup (with a spout) to slightly cool.
  • In a small mixing bowl, add the 3 egg YOLKS. Blend with an immersion blender just until lemon juice is incorporated.
  • Pour butter into egg/lemon mixture in a little at a time and blend with immersion blender until thick and creamy.
  • Blend in the shallot reduction and tarragon followed by the salt and pepper.; adjust taste, if needed. Refrigerate at least an hour before using to allow flavors to meld.
  • Spoon sauce on meat or vegetables. Refrigerate leftovers promptly.
