Step 1: Gather all your ingredients and measure them out to ensure a smooth preparation process.
Step 2: In a medium mixing bowl, combine the mayonnaise and apple cider vinegar. Whisk these two ingredients together until the mixture is smooth and creamy.
Step 3: Gradually add the sugar (or honey, if using) to the mayonnaise mixture, whisking continuously until the sweetener is completely dissolved and the sauce is smooth.
Step 4: Stir in the Dijon mustard, onion powder, and garlic powder. Season with salt and black pepper to your preferred taste. Mix everything until all ingredients are well combined.
Step 5: Taste the sauce and adjust the sweetness or tanginess as needed. You can add a little more sugar for extra sweetness or a splash more apple cider vinegar for a tangier profile.
Step 6: Cover the bowl with plastic wrap and refrigerate the sauce for at least 30 minutes. This chilling time allows the flavors to meld beautifully and the sauce to thicken slightly. Serve on your favorite sandwiches, salads, or as a delicious dipping sauce!
