Total crowd-pleaser. Delicious served as a salad dressing or dip.
In a medium bowl, whisk together the mayonnaise, sour cream, Worcestershire, lemon juice, vinegar, chives, buttermilk and blue cheese until fully combined.
Store in an airtight container in the refrigerator for up to one week.
If you don't have buttermilk or heavy cream on hand, you can substitute with whole milk. The final result will still be delicious, just slightly less creamy.
