In a small bowl, whisk together the mayonnaise, water, ketchup (or tomato paste), sugar, garlic powder, paprika, salt, ground ginger, and onion powder until smooth.

Cover the bowl with plastic wrap or a lid and refrigerate for at least 1 hour to allow the flavors to develop.

Stir well before serving. Use as a dip, drizzle, or spread with your favorite dishes.
