Kenny's BBQ Sauce Clone

After some research and testing, here is a pretty darn close replica of the BBQ sauce at the Kenny's Ribs & Chicken restaurants in Chicago.  Kenny's sauce in the store is made from a lot of processed ingredients like corn syrup and preservatives. Here's a more fresh version.

6 oz. can of tomato paste
1 C water
1/2 C distilled vinegar
Juice from 1/2 lemon
3T sugar
3T brown sugar
2 t molasses
1 t salt
1 t mustard powder
1/2 t onion powder
1/4 t garlic powder

To make it hot, add 1/2 t of cayenne.

Mix and simmer on stove for 10 minutes.
