Ingredients:

1 ½ cups ketchup
1 cup Coca-Cola classic
¼ lb. butter (1 stick)
½ cup dark brown sugar, packed
¼ cup Worcestershire sauce
Salt, pepper, seasoning salt, cayenne pepper and garlic to taste

Directions:

Combine all ingredients in saucepan; simmer over low heat for 20-30 minutes. Enjoy immediately or store in a jar and refrigerate for next time. Can be served with beef, chicken, pork, or just about any other kind of meat. It also works well as a dipping sauce for bread.

A variation from fellow Saints Tailgater Lee D.

I found that the Coke Classic tends to thin out the sauce too much, I prefer a thicker sauce. I either slowly reduce the Coke by itself or buy Coke syrup from a local drug store. I can then thin out the syrup accordingly. I also add either (or sometimes both) dried/powdered cayenne or chipotle to taste. At times and under the influence of alcohol I've even added liquid crab berl for that extra little something on otherwise bland chicken.
