1/4 cup white wine or champagne
1 to 3 teaspoons Dijon mustard
1 teaspoon kosher salt
Freshly ground black pepper to taste
2/3 cup extra-virgin olive oil
2 tablespoons minced herbs, such as tarragon, chives, and/or parsley
The herbs will loose their vibrant green color over time, but will contribute but will contribute more flavor to the dressing.
