Take a clean mixing bowl and add mayonnaise. Make sure it is fresh and smooth. This will be the creamy base for your dressing. Use a spoon to stir it slightly before adding other ingredients.

Add sugar, white vinegar, and lemon juice into the bowl. These ingredients give the dressing its signature sweet and tangy taste. Mix slowly until everything blends smoothly with the mayonnaise.

Add salt, black pepper, garlic powder, and onion powder. Stir well so the spices spread evenly. The mixture should start smelling flavorful and slightly savory at this stage.

Add mustard for extra depth and flavor. Then pour in milk to thin the dressing slightly. Whisk everything until the texture becomes smooth and creamy without lumps.

Taste the dressing carefully. Add more sugar if you want sweetness or more vinegar for tanginess. Adjust seasoning slowly until you reach your perfect balance of flavor.

Pour the dressing into a clean jar with a lid. Refrigerate for at least 30 minutes before using. This helps all flavors blend together and taste richer.
