Put the mayonnaise, buttermilk, sour cream, Parmesan, balsamic, Worcestershire, anchovies, garlic and some salt and pepper into a blender or food processor and pulse the processor or blend on low speed for several seconds. Adjust the consistency if needed with a little extra buttermilk. Refrigerate the dressing for a few hours (it just gets better!) before using it on the salad.
You can thin with a little fresh lemon juice or squeeze a lemon slide in for flavor. |
