Prepare the Ingredients. First, gather all the ingredients on your kitchen counter. Having everything ready will make the process smoother and more enjoyable.
Mix the Ingredients. Next, in a medium-sized bowl, combine the mayonnaise, ketchup, rice vinegar, sesame oil, garlic powder, onion powder, paprika, sriracha, and Stevia. Use a whisk or a spoon to mix the ingredients thoroughly until well combined. The result should be a smooth and creamy sauce with a beautiful pink hue.
Taste and Adjust. Then, take a spoonful of the Yum Yum Sauce and give it a taste. Adjust the seasonings to suit your preference. If you prefer it tangier, add more vinegar. If you like it sweeter, increase the sugar substitute.
Let it Rest. Next, cover the bowl with plastic wrap or transfer the sauce to an airtight container. Allow the flavors to meld by refrigerating the Yum Yum Sauce for at least 30 minutes. This resting time will intensify the flavors, giving you the best version of your homemade sauce.
Serve and Savor. Finally, your homemade Yum Yum Sauce is ready to be savored!
