Sweet and Sour Barbecue Sauce Recipe

Directions:

1. In a large pan, heat oil over medium heat and fry the onion until golden brown, about 10 minutes.
2. Add garlic. Stir and cook 1 minute.
3. Add tomatoes, pineapple, vinegar, molasses, brown sugar, tomato paste, mustard, paprika, oregano, chipotle powder and pepper. Bring to a boil. Lower heat and simmer, stirring occasionally, for 2 hours, or until thick. Let cool slightly.
