In a medium bowl, combine mayonnaise, sour cream, and buttermilk.
Whisk until smooth to create a creamy base.
Add ghost pepper paste and mix well.
The paste brings the signature heat, so adjust for your spice preference.
Stir in chopped parsley for a fresh herb flavor that complements the other ingredients.
Sprinkle garlic powder, paprika, chili powder, salt, and black pepper into the mixture.
These spices enhance the sauce's flavor complexity.

This step is key for developing the sauce's robust taste.
