1. Gather all the ingredients needed for the recipe: mayonnaise, Parmesan cheese, white vinegar, sugar, garlic powder, onion powder, black pepper, crushed red pepper flakes (optional), dried parsley, and water.
2. In a medium-sized mixing bowl, combine the mayonnaise, grated Parmesan cheese, white vinegar, and sugar. Mix thoroughly until the ingredients are well blended.
3. Add in the garlic powder, onion powder, black pepper, and crushed red pepper flakes if you prefer a hint of spice. Stir well to distribute the seasonings evenly throughout the mixture.
4. Gradually add water one tablespoon at a time to adjust the sauce to your desired consistency. The sauce should be creamy and thick enough to coat wings or other foods without being too runny.
5. Taste the sauce and make any adjustments needed. If the flavor requires more garlic, add a little extra garlic powder. For a spicier version, increase the amount of red pepper flakes.
6. Transfer the sauce to a small saucepan over medium heat to simmer gently. Stir occasionally for 5-10 minutes to allow the flavors to meld together.
7. Remove the sauce from heat and let it cool slightly. As it cools, it will thicken further, making it perfect for serving or storing.
8. Serve immediately or place the sauce in an airtight container and refrigerate for later use.
9. Enjoy this versatile sauce as a coating for wings, a dip for snacks, a pasta topper, or in any other creative way you like.
