OK, the easiest home-made sauce I know is honey, soy and garlic with a little chicken stock. About 1/4 cup of soy with 1/2 cup of chicken stock and honey and garlic to taste (about 1 tbs of honey and 2 cloves of garlic is my choice!) You can mess around with it, add grated onion, herbs, ginger or a little cornflower to thicken and then it's great as a sauce for wings or drumsticks.
Christy's recipe sounds great too though!
