In your blender, mix together diced mango, ketchup, apple cider vinegar, brown sugar, soy sauce, lime juice, garlic powder, smoked paprika, salt, and pepper. Blend until perfectly smooth, or pulse for a chunkier texture.

Transfer the mixture to a saucepan and bring it to a simmer over medium heat. Once simmering, reduce the heat and cook for 5 minutes, stirring occasionally, until the sauce thickens. Allow it to cool before serving. Store it in an airtight container in the fridge.
