Years ago when I was just a young lad. Not that I'm much older now. I tasted a blackberry BBQ sauce that has been perplexing me for almost 10 years now. It was the greatest thing I ever tasted as a bbq sauce. The chef put it over some tenderloin chunks and by far has been one of my favorite meals to this day. I've never been able to re-create the sauce myself but Im hoping someone in here has a good blackberry bbq sauce recipe they are willing to lend out for testing.
