I sometimes braise with oyster sauce. Rough ratio:
2 cups chicken stock
4 TBsp oyster sauce
3 TBsp sake rice wine
3 tsp soy sauce
2 tsp sesame oil (to taste)
1 pinch black pepper (to taste)
Stuff like tofu, bok choy, and broccolini.
You can thicken it at the end with a corn starch slurry.
Or, you can add additional chicken stock to taste for a soup base that's tasty, too.
