I have a very simple yet tasty recipe for marinating chicken:
Salt (if needed)
Black pepper (optional)
It's pretty straightforward, really. You just cut the chicken if you need to, sprinkle the spices, splash the sauce and mix well. Lick your finger to make sure everything tastes right but is not too salty. Coriander doesn't have a strong flavor, so be a bit more liberal with it. Chicken does not have to drown in soy sauce, but there should enough of it to soak the chicken well. Place it in a fridge for an hour or more.
