Notes
If you don't have Worcestershire sauce available, then leave it, and add 3 - 4 tsp brown sugar (or as per taste) to the soup. You can also replace this worcestershire sauce with bbq sauce for a change.Since thse sauce already ahs sweet content, you don't need to add extra sweetener if using these.
