Blend until pureed. Strain the puree, then pour into a small saucepan.
Add all the other ingredients, and cook on the stove on med/high heat until it boils. Then turn back to a simmer, and cook out the water until it reaches the desired thickness.
(Keep in mind... this won't be as thick as "Sweet Baby Rays.")
Also, if you don't want to watch it simmer for hours, you can cook it in your crockpot uncovered for the amount of desired hours. I did 4 or 5 hours, but I uncovered it way later...not in the beginning.
When done cooking, pour into pint jars, and hot water bath them. You can look online how to do that. I did the batch 5x, so if you like your BBQ then go for i!!!
