cup fresh lemon juice
tablespoons chopped fresh tarragon
tablespoon red wine vinegar
teaspoons Dijon mustard
cup olive oil
Process lemon juice, chopped shallot, chopped fresh tarragon, red wine vinegar, sugar, Dijon mustard, salt, and pepper in a blender until smooth. With blender running, add olive oil in a slow, steady stream, processing until smooth. Turn off blender; add pistachios, and pulse until pistachios are finely chopped. Drizzle 1 lb. grilled asparagus with 3 to 4 Tbsp. vinaigrette, or try it over grilled salmon or other meat. Store any remaining vinaigrette in an airtight container in refrigerator 3 to 5 days.
