you can also try finding the top secret recipes web site ( i think it is www.topsecretrecipes.com but i could be wrong...do a search)....this guy has whole books and online recipes of 'copy cats' of things that you find in restaurants and stores....if you have a particular brand of sauce that you think is close...like kc masterpiece...or something like that. then you can start with that basic recipe and tweak it so it fits your own tastes....that way you already are starting from a good flavored base recipe and when you add those special extras during the cooking it will really taste better than trying to add stuff to the store bought stuff after it has been cooked and bottled....
