1. Combine all of the BBQ sauce ingredients into a small saucepan. Whisk until thoroughly combined, then simmer over medium heat until it's reduced by about a third. If it starts to stick to the bottom of the pan, reduce heat to medium-low. It'll take 15-25 minutes for the sauce to thicken up and coat the back of a spoon. 2. Use on grilled chicken breasts. Transfer 1/2 cup of the finished BBQ sauce to a small bowl. Brush chicken with the 1/2 cup (or more) BBQ sauce for the last 2-3 minute of cooking. Serve additional sauce with chicken.
