Homemade Blue Cheese Dressing

1 1/2 cup Mayonnaise
1 cup buttermilk
*** You may use more or less of either buttermilk or mayonnaise depending on how thick you want your dressing. Remember as you let the dressing chill, it will become slightly thicker.
1 teaspoon accent
1 teaspoon onion powder
1 teaspoon garlic powder
1 teaspoon coarse black pepper
1 teaspoon salt
2 tablespoon parsley flakes
1/4 cup crumbled blue cheese

Combine all ingredients except crumbled blue cheese in a bowl. Mix with wire whisk until smooth. Add in blue cheese and stir with spoon. Add time to chill before serving: This is pretty mild if you like more blue cheese add it.
