Preparation:
1. Combine all of the ingredients for the barbecue sauce in a saucepan over high heat. Blend the ingredients with a whisk until smooth.
2. When the mixture comes to a boil, reduce the heat and simmer uncovered.
3. In 30 to 45 minutes, when the mixture thickens, remove it from the heat. If you overcook it and make the sauce too thick, thin it with more vinegar. |
