In a medium bowl, whisk together mayonnaise, white vinegar, and lemon juice until smooth. No lumps, no drama.
Stir in apple juice or water to loosen it up to your desired creaminess. If you want it thicker, add a bit less; if you want it saucier, add more.
Beat in garlic powder, onion powder, salt, pepper, and cayenne. Taste and adjust seasonings like a pro—you’re basically a flavor DJ at this point.
Cover and refrigerate for at least 30 minutes. Letting it mingle makes the flavors pop; your future self will thank you.
Give it a quick stir before serving. If it’s too thick, splash in a tad more juice or water.
