Whisk everything together in a bowl until smooth and emulsified. Taste and adjust—more sugar/vinegar for sweet-tang balance, more paprika/smoke for BBQ vibe, more mustard for bite.
For thicker texture (like the bottle), blend briefly with an immersion blender or add a pinch of xanthan gum (optional, ⅛ tsp).
Let it sit in the fridge for at least 30-60 minutes (ideally a few hours or overnight) for flavors to meld.
Shake/stir before use. Store in a jar in the fridge for up to 1-2 weeks.
