In a medium-sized mixing bowl, measure and combine ¾ cup Mayonnaise, ½ cup Buttermilk, and 2 Tablespoon Distilled white vinegar using a wire whisk until the liquid dressing base is completely smooth and uniform.
Carefully measure and add your dry seasoning blend directly into the bowl, including 2 teaspoon smoked paprika, 1 teaspoon garlic powder, ½ teaspoon onion powder, ¼-½ teaspoon cayenne pepper, ½ teaspoon black pepper, ½ teaspoon kosher salt, and ¼ teaspoon mustard powder.
Whisk the entire mixture vigorously for about 1 minute until all of the dry spices are fully incorporated into the creamy base and no stubborn pockets of dry seasoning remain.
Gently fold in the secret flavor boosters consisting of 1 Tablespoon Fresh chives (finely minced), ½ teaspoon Granulated white sugar, and ¼ teaspoon MSG using a silicone spatula until they are evenly distributed.
Cover the bowl tightly with a piece of plastic wrap, or transfer the mixture into an airtight mason jar, and place it inside the refrigerator to chill for at least 30 minutes before serving.
