If you really want a sauce, I recommend this one that I use for pulled pork. I wouldn't cook with it, just use it as a sauce after cooking.
1 medium onion, coarsely chopped
1/2 cup cider vinegar
1/2 cup ketchup
1/4 cup light (mild) molasses
2 tbsp sweet paprika
2 tbsp spicy brown mustard
2 tbsp Worcestershire sauce
1 tsp cayenne pepper
1 tsp black pepper
1 tsp salt
1/4 cup water
1/2 tsp liquid smoke flavoring (optional)
Oh yeah, get some rhubarb, dice and put in a cheesecloth bag. That'll make it really special. Possibly add raspberry puree to the sauce as well.
