Combine Ingredients: In a medium mixing bowl, add the mayonnaise, ketchup, yellow mustard, honey, apple cider vinegar, garlic powder, paprika, and cayenne pepper.
Whisk Together: Using a whisk or a fork, mix all the ingredients together until well combined and the sauce achieves a smooth, consistent texture.
Season: Taste the sauce and then season with salt and black pepper as per your preference. Adjust the cayenne pepper if you desire a spicier kick.
Chill: For the best flavor, cover the bowl with plastic wrap and refrigerate the sauce for at least 1 hour before serving. This enables the flavors to harmoniously blend together.
Serve: Your Sonic Signature Sauce is now ready to enjoy! Serve it as a dip for fries, chicken tenders, or as a spread for burgers and sandwiches.
