Eh, no offense intended to the posters, but you aren't going to make most of those sauces. I defy you to make your own soy or hoisin sauce. I cook a lot, and no matter what recipes I use, I never get oriental sauces to taste like what you get in restaurants, mainly because they buy most of their sauces too. Supposedly the sweet and sour sauce can be made, but when i go to someone's house who says they make it from scratch it is never close.
Sometimes I make my own barbque sauce, but many of the asian sauces are just not feasable to make. Even if you could, it would be vastly cheaper and save you hours just to go to a good asian store and pick them up.
