Blue Cheese Dressing

There is a nearly fat-free blue cheese salad dressing recipe on this website, but if you are looking for something just a tad bit more indulgent, I also offer this mixture. Super awesome with Super Bowl Buffalo Wings.
 
1/2 cup mayonnaise (such as Best Foods/Hellman's)
1/2 cup buttermilk
1/2 cup sour cream
1/2 cup crumbled Blue Cheese (such as Rogue Creamery)
1 Tablespoon white wine vinegar
1/2 teaspoon garlic powder
1/4 teaspoon Kosher salt
1/2 teaspoon ground black pepper
2 Tablespoons finely minced fresh Italian flat-leaf parsley
 
Mix all ingredients in a small bowl. Stir well to combine. Let rest at least two hours before serving. Keeps one week, covered and refrigerated. Makes two cups.
