Smokin,

Here's the Sweet Vinegar Sauce recipe. It's a sauce that I found a while back and tweaked a little. The original was too sweet for me. It's still pretty sweet.
Sweet Vinegar Sauce

1 cup cider vinegar
� cup Karo syrup
� cup brown sugar
1 Tbs dehydrated onion
1 Tbs red pepper flakes
5 Tbs Crystal hot sauce

Simmer till sugars are dissolved then refrigerate for 24 hrs to let flavors mingle.

what are the amounts on the br. sugar and Karo syrup..and is it the dark?

I would venture to say they are 1 cup, or they would have read CUPS?

As for the Dark, your guess is as good as mine, and mine is not too good usually!
