DWAIN,
I retasted the OBQ Sweet and I am now of the opinion that it's unique taste is from the use of cinnamon, cardamon and clove.
STEVE,
I started down this path in an effort too see what some of the winning rubs taste like in an effort to create a "winning" rub.
What I have learned is this, there really is no consistant theme amongst these winning rubs but you seperate them into 4 distinct styles.
Some are heavy pepper...
Some are heavy paprika...
Some are heavy sugar...
Some are heavy salt...
The funny thing is that 3 of the more popular rubs out there (Head Country, Butt Rub & Blues Hog) each fall into a different style.
So far, I have liked the heavy pepper rubs with a sweet BBQ sauce.
However, most of my taste testers liked heavy sugar rubs with a sweet bbq sauce.
It beat out heavy salt rubs with a sweet sauce by a narrow margin.
Anyway, while my taste testing is nowhere near done yet, it has confirmed some of my previously formed beliefs...
1) I eat spicer and hotter than most.
2) Most people love SWEET.
