Ingredients
2 medium shallots, finely minced
1 1/2 cups dry white wine
1/2 cup white-wine or Champagne vinegar
1 cup (2 sticks) cold unsalted butter, cut into tablespoons
Coarse salt and freshly ground pepper
2 tablespoons chopped fresh herbs, such as tarragon, basil, parsley, and chives
Preparation
In small saucepan, combine shallots, wine, and vinegar. Bring to a boil, reduce heat to medium, and simmer until liquid is reduced to 2 tablespoons, about 10 minutes.
Turn down heat to lowest possible flame. Whisk in butter, 1 tablespoon at a time, adding a piece as previous one melts. Don’t allow sauce to become too hot. For a more smooth sauce, strain through a fine sieve, if desired.
Season with salt and pepper and keep over a bain-marie. Just before serving, stir in herbs.
