• For best flavor, I prefer whole milk sour cream and buttermilk and regular mayonnaise. If you use reduced fat varieties, start with the lesser amount of vinegar.
• Greek yogurt may be used instead of the sour cream. Again, whole milk yogurt offers the smoothest taste.
• For chunkier dressing, increase the blue cheese by an additional ¼ cup or to taste.
• For a thinner consistency, drizzle in an extra tablespoon or two of buttermilk.
• For a thicker consistency, reduce the buttermilk by a tablespoon or two and/or add additional blue cheese.
• For a smooth consistency, you could blend the dressing in a blender or food processor.
• For an herby blue cheese, use 5 or 6 tablespoons fresh herbs. In this case, I like 3T parsley, 2T chives, and 1T dill.
