Add all the ingredients for your chosen version of the Yum Yum sauce into a small mixing bowl or jar, making sure everything is measured accurately for balanced flavor.
Whisk the mixture thoroughly until the sauce becomes completely smooth, creamy, and evenly blended with no visible lumps.
Taste the sauce and adjust the seasoning with salt, pepper, or additional chili garlic sauce depending on your preferred flavor.
Cover the bowl or transfer the sauce to an airtight container and place it in the refrigerator.
Let the sauce chill for a while before serving so the flavors can fully develop and deepen.
Stir gently before serving to ensure the texture remains smooth and consistent.
