This classic, creamy butter-tarragon sauce is fancy, but effortless thanks to this simplified blender preparation. Be sure the butter is hot when you add it to the blender; adequate heat allows the butter to cook the eggs as they blend together.

1/4cupChampagne or white wine vinegar
1/4cupdry white wine, such as sauvignon blanc or pinot grigio
1shallot, minced
2Tbspchopped fresh tarragon, plus a bit more for garnish
In a small saucepan, combine the vinegar, white wine, shallot, 1 tablespoon of the tarragon, 1/4 teaspoon salt and 1/4 teaspoon pepper. Bring to a boil and lower to a simmer over medium heat until the mixture is reduced to a few tablespoons, about 5 minutes. Cool slightly.
Transfer the cooled mixture to a blender and add the egg yolks and 1 teaspoon salt. Blend for 30 seconds. With the blender on, slowly pour the hot melted butter through the opening in the lid. Add the remaining tarragon leaves and pulse for a few times.
If the sauce is too thick, add a tablespoon of water to thin. Garnish with a little chopped tarragon and serve immediately.
