Bourbon BBQ Sauce

I'm posting this for my own information so that I can scale it down. It comes from my friend that owns his own Southern Inspired Cuisine restaurant.

• 1 (32 ounce) can plum tomatoes, pureed

2. Add garlic and cook 2 minutes more.
3. Add chili powders and cook 5 minutes mixing well with the onion and garlic.
4. Add tomato, water, ketchup, mustard, molasses, brown sugar, honey and vinegar. Cook on low heat about 20 minutes or until it gets thick.
