Since the time is upon us and id like to create my own sauce. My problem is I only know of a few things that go in a bbq sauce. Ketchup, brown sugar, I've heard of mustard being used and assorted spices. But what makes a good one? My next problem Is I also might need to make it diabetic friendly as I have family that has diabetes, so if it's diabetic friendly AND tastes good to non diabetics that'd be great.
