Mix it up: In a small saucepan, combine Stubbs Spicy BBQ Sauce, ketchup (if using), and apple cider vinegar. Stir until smooth.
Add sweetness and spice: Stir in honey or brown sugar, paprika, garlic powder, pepper, and salt. If you crave more heat, sprinkle in a pinch of cayenne.
Simmer briefly: Bring to a gentle simmer over medium heat, then reduce to low. Let it bubble softly for 5–7 minutes, stirring occasionally.
Taste test: Give it a quick taste. Adjust salt, sweetness, or heat as you like. Remember: you can always add more, but you can’t un-add it.
Finish: Remove from heat. If you want it ultra-smooth, give it a quick blitz with a whisk or a blender for 10 seconds.
