Start by making the creamy pepper sauce. In a bowl, whisk together mayonnaise, white vinegar, lemon juice, Dijon mustard, and mustard powder. Stir in the chipotle peppers for a little kick. Add in the cracked black pepper, white pepper, salt, smoked paprika, garlic granules, onion granules, parsley flakes, and smoked chili flakes. Mix well. Set aside to let the flavors meld.
