Erin's Chipotle Barbecue Sauce

This took a while to perfect, but I finally got it.  I'm working on a bourbon version right now!

Chipotle Barbecue Sauce

2 C ketchup
1 C water (you can also use 1/2 C water and 1/2 C bourbon)
1/2 C apple cider vinegar
1/4 C molasses
1/4 C honey
3/4 C sugar
1/2 tbs black pepper
1/2 tbs. onion powder
1/2 tbs. mustard
Juice of 1/2 a lemon
1-2 tbs pureed chipotle in adobo (more or less depending on your taste and spice tolerance)
1 tbs Worcestershire sauce

Combine all ingredients in a large saucepan and mix well (I whisk).  Bring to a boil, reduce heat to a simmer.  Cook, uncovered, for 1 1/2 hours, stirring occasionally.

Yields about 3 1/2 cups
