Amazingly it isn't that difficult to make your own sauce and you are smug in the knowledge that you know what is in it. I wanted something smoky with a kick to it- so I added a bit of the pureed chipotle paste I keep in the fridge (just blitz a can of chipotles in adobo and put in a sealable jar).
This is a piece of cake- it's good with steak too.
Xoch's Sweet and Spicy BBQ Sauce
Enough for 4 drumsticks with plenty leftover to dip in
4 tbsp. ketchup (to add to your feelings of smugness use an organic version)
2 tbsp. Chipotle paste
3 tbsp. white wine vinegar
1 tbsp. brown sugar
1 tbsp. Worcester sauce
Mix everything together in a bowl until well blended.
