Sunset Magazine had a barbecue contest a few years back and this sauce was the grand prize winner. Not long after, a group of friends got together with ribs from the two best ribs places in the area for a ribs taste test. We got a variety of their sauces and I also made the Sunset recipe. There was no contest. The sauces from the ribs joints couldn't hold a candle to the Sundset blackberry BBQ sauce. This is the best!
This makes 1 1/3 cups:
Whirl all in a blender until the berries are pureed.
Pour into a 1 quart glass measuring cup. Cover loosely with a microwave-safe plastic wrap, leaving a vent for steam.
Cook in a microwave oven at full power, stirring occasionally until berry mixture is reduced to 1 1/3 cups, about 8 minutes. Serve with anything barbecued.
