Fresh Blueberry Barbecue Sauce

In a medium saucepan, heat the oil over medium-high heat until shimmering. Add the onion and cook until tender, about 2 minutes. Add garlic and cook until fragrant, about 1 minute.
Then add the blueberries, water, honey and vinegar. Bring sauce to a boil. While boiling, add chili powder, cumin, salt, pepper, garlic powder, smoked paprika, molasses and Worcestershire sauce to the saucepan.
Continue to boil about 5 minutes, stirring constantly until thickened. Remove from the heat and let the sauce cool 5 minutes.
Use an immersion blender, stand blender or food processor to blend the sauce until smooth.
Use immediately or store in a covered container in the refrigerator for up to 2 weeks.
