In a small bowl, whisk the mayonnaise and sour cream until smooth. No lumps, no drama.
Stir in ketchup, mustard, and pickle relish. The color should be tasty and not suspiciously beige.
Add hot sauce, garlic powder, and onion powder. Give it a vigorous whisk; you want the flavors to wake up.
Season with salt, pepper, and a splash of lemon juice if you’re feeling zippy. Taste and adjust—we’re aiming for balanced tang, not a tang-tag.
Cover and chill for 15–30 minutes if you have the time. If you don’t, yeah, it still tastes good now—just a touch more chaotic.
